First: Statements from Some Companions and Tabi'een (Followers) Regarding the Name of Allah "Ar-Raheem" and the Distinction between "Ar-Raheem" and "Ar-Rahman"
Ibn Abbas (may Allah be pleased with him):
Ar-Rahman (the Compassionate) is gentle, and Ar-Raheem is affectionate towards His creation by providing sustenance. Both names are delicate, but one is more tender than the other. It is also reported that he said: "Ar-Rahman is the gentle with His servants, and Ar-Raheem is affectionate towards them."
Mujahid (may Allah have mercy on him):
Ar-Rahman is compassionate towards the people of this world, and Ar-Raheem is merciful to the people of the Hereafter. This is reflected in a prayer: "O Rahman of this world, O Raheem of the Hereafter."
Ad-Dahhak (may Allah have mercy on him):
Ar-Rahman is compassionate to the inhabitants of the heavens, where He placed them in the heavens, surrounded them with obedience, and protected them from calamities and desires. Ar-Raheem is compassionate to the people of the earth, where He sent messengers to them and revealed scriptures.
Ikrimah (may Allah have mercy on him):
Ar-Rahman refers to one mercy, while Ar-Raheem refers to a hundred mercies.
Ibn al-Mubarak:
Ar-Rahman answers when asked, but Ar-Raheem becomes displeased when not asked.
Ata’ al-Khurasani:
Ar-Rahman was one of Allah's names that none of His creation could claim. But when Musaylimah the Liar claimed it for himself, Allah clarified that He is "Ar-Rahman Ar-Raheem" to distinguish His name from the one falsely claimed by others.
Abu Bakr Muhammad ibn Umar al-Warraq:
Ar-Rahman is the one who bestows blessings and bounties, while Ar-Raheem withholds harm. He also said: "Ar-Rahman with those who disbelieve, and Ar-Raheem with those who believe."
Muhammad ibn Ali al-Mazeedi:
Ar-Rahman saves from the fire, as in the verse: "And you were on the edge of a pit of the Fire, and He saved you from it." Ar-Raheem grants entry into Paradise, as in the verse: "Enter it in peace, secure."
Al-Muhasibi:
Ar-Rahman refers to mercy over bodies, and Ar-Raheem to mercy over hearts.
As-Sari ibn Mughlis:
Ar-Rahman removes distress, and Ar-Raheem forgives sins.
Abdullah ibn Jarrah:
Ar-Rahman guides on the path, and Ar-Raheem grants protection and success.
Mutahhar ibn al-Warraq:
Ar-Rahman forgives great sins, even if they are numerous, and Ar-Raheem accepts small acts of obedience, even if they are few.
Yahya ibn Mu'adh ar-Razi:
Ar-Rahman deals with the needs of this worldly life, while Ar-Raheem ensures the affairs of the Hereafter.
Al-Husayn ibn al-Fadl:
Ar-Rahman shows mercy to His servant by removing harm, and Ar-Raheem is the one who feels compassion to His servants.
Muqatil ibn Sulayman:
Ar-Rahman and Ar-Raheem are two delicate names, with one being more tender than the other. Ar-Rahman signifies compassion, while Ar-Raheem refers to showing mercy to His creation.
These reflections highlight the nuanced distinctions between "Ar-Rahman" and "Ar-Raheem," emphasizing different aspects of Allah’s boundless mercy in this life and the Hereafter.
Second: Statements from Some Mufassireen (Qur'anic Exegetes) on the Name of Allah "Ar-Raheem" and the Difference Between It and "Ar-Rahman"
1- At-Tabari said:
Ar-Raheem is derived from the root word "rahm" (mercy). If someone says: “Since both ‘Ar-Rahman’ and ‘Ar-Raheem’ are derived from the word mercy, why repeat it when one of them conveys the meaning of the other?”
The answer is: That is not the case. Each word has its own meaning that the other cannot fully convey.
If it is asked: “What is the distinct meaning of each that makes one different from the other?”
It is said: In terms of the Arabic language, there is no disagreement among scholars of the Arabic language that the word Ar-Rahman is more intensive in its expression than Ar-Raheem. As for the transmitted reports and narrations, tafsir scholars differ:
Al-Arzami said: Ar-Rahman refers to Allah’s mercy over all of creation, while Ar-Raheem is specific to the believers.
Ibn Mas'ud (through a chain) narrated that the Prophet Muhammad (peace be upon him) said: Ar-Rahman is the Compassionate One over the affairs of both the Hereafter and the world, while Ar-Raheem is the Merciful One of the Hereafter.
These reports indicate a difference between Allah's name Ar-Rahman and His name Ar-Raheem, and they reflect the different meanings of these two words. Although these reports differ on whether this distinction applies to the world or the Hereafter, both show that there is a difference in meaning.
If asked: "Which of these interpretations is more correct?"
The answer is: Both are correct, and there is no reason to prioritize one over the other. This is because the meaning of Ar-Rahman describes Allah's general mercy towards all of His creation, while Ar-Raheem refers to His specific mercy towards some of His creation, either at all times or in certain circumstances.
There is no doubt that this specific mercy applies to the believers, both in this world and the Hereafter, as Allah has shown His kindness to them by guiding them to obedience, belief in Him, and following His commands, while He has withheld this from the disbelievers. Additionally, in the Hereafter, Allah has reserved eternal bliss in Paradise for the believers, while disbelievers are denied this.
Our Lord, the Almighty, is Ar-Rahman to all of His creation in both this world and the Hereafter, and He is Ar-Raheem specifically to the believers.
In this world, Allah's general mercy is extended to all of His creation through His blessings, like sustenance, rain, and health, as mentioned in the verse: “And if you count the blessings of Allah, you will never be able to enumerate them” (Qur’an: 14: 34, and Qur’an: 16: 18).
In the Hereafter, His general mercy will manifest in the form of absolute justice for everyone. No one will be wronged, and good deeds will be multiplied. Every soul will receive what it earned. This is Allah's general mercy in the Hereafter.
However, His special mercy for the believers in this world includes the guidance and protection in religion, as He says: “And He is ever Merciful to the believers” (Qur’an: 33: 43).
In the Hereafter, this special mercy for the believers will be manifested in the eternal bliss and honor He has prepared for them, which far exceeds all expectations.
[Source: Tafsir At-Tabari, Volume 1, Pages 126-129].
2- As-Samarqandi:
Ar-Raheem refers to Allah being especially gentle towards the believers, covering their sins in this world, showing them mercy in the Hereafter, and admitting them to Paradise. It is also said that Allah named Himself Ar-Raheem because He does not burden His servants with more than they can bear, unlike other kings who may demand everything from their people. Hence, those kings are not truly merciful.
Ali ibn Abi Talib (may Allah be pleased with him) said about the statement "In the Name of Allah": "His name is a cure for every disease and help for every remedy. Ar-Rahman is help for those who believe in Him, and it is a name that no one else can bear. As for Ar-Raheem, it is for those who repent, believe, and do righteous deeds."
(Bahr Al-Uloom, by Nasr ibn Muhammad As-Samarqandi, 1/14)
3- Maki ibn Abi Talib:
Ar-Raheem means that Allah is compassionate towards His creation by providing them sustenance and other needs. Ar-Rahman was mentioned first because it is an exalted name exclusively for Allah, while Ar-Raheem may also describe creation. It is said that Ar-Raheem was mentioned after Ar-Rahman to teach people that the combination of "Ar-Rahman Ar-Raheem" belongs solely to Allah. Although Musaylimah the liar claimed the name "Ar-Rahman," no one else can be named "Ar-Rahman Ar-Raheem" together, as these names are exclusive to Allah.
(Al-Hidayah ila Bulugh an-Nihayah, by Maki ibn Abi Talib, 1/97-98)
4- Al-Mawardi:
Ar-Raheem is derived from the attribute of mercy. Therefore, Ar-Rahman and Ar-Raheem were combined to remove confusion. In Arabic, Ar-Raheem should precede Ar-Rahman, but Ar-Rahman was mentioned first due to its greater intensity. Ar-Rahman is more emphatic than Ar-Raheem, as Ar-Rahman extends in both its meaning and expression, while Ar-Raheem is limited to its meaning. This is why some people are called "Raheem," but no one is called "Rahman," except for Allah. Even in pre-Islamic times, Allah was called Ar-Rahman, as indicated in poetry by Ash-Shanfarah. When Musaylimah claimed the name Ar-Rahman, Allah paired it with Ar-Raheem to distinguish His name.
(Tafsir Al-Mawardi, 1/52-53)
5- Al-Baghawi:
Scholars differ regarding Ar-Rahman and Ar-Raheem. Some say they are synonyms, similar to "Nadman" and "Nadim," both meaning compassionate. Others distinguish between them by saying Ar-Rahman refers to Allah’s universal mercy in this world, while Ar-Raheem is specific to the believers in the Hereafter. The common supplication reflects this: "O Rahman of this world, O Raheem of the Hereafter." Ar-Rahman is the One whose mercy reaches all of creation, while Ar-Raheem refers to a mercy that reaches only some. Thus, people may be described as "Raheem," but only Allah is called Ar-Rahman.
(Ma'alim at-Tanzil, by Al-Baghawi, 1/71-72)
6- Fakhr ad-Din ar-Razi:
Mercy (Ar-Rahma) is the removal of afflictions and the granting of goodness to those in need.
(Mafatih al-Ghayb, by Fakhr ad-Din ar-Razi, 1/24)
7 - Al-Qurtubi:
Scholars have debated whether Ar-Rahman and Ar-Raheem have the same meaning or different meanings. Some say they are the same, like "Nadman" and "Nadim," while others argue that Ar-Rahman is a name used only for Allah, denoting His universal mercy, while Ar-Raheem specifically refers to His mercy towards the believers. Ar-Rahman encompasses all creation in the dunya (world), and Ar-Raheem focuses on the Hereafter.
(Al-Jami' li Ahkam al-Quran, by Al-Qurtubi, 1/105)
8 - Al-Baydawi:
Ar-Rahman and Ar-Raheem are both derived from "rahma" (mercy), emphasizing different levels of mercy. Ar-Rahman is more emphatic, encompassing both believers and non-believers in this world, while Ar-Raheem refers specifically to the believers.
(Anwar at-Tanzil wa Asrar at-Ta'wil, by Al-Baydawi, 1/27)
9 - As-Samin al-Halabi:
Ar-Rahman and Ar-Raheem are both derived from mercy. Some argue that Ar-Rahman is not derived, as the Arabs did not recognize it, as shown in their question: "What is Ar-Rahman?" However, Ibn al-Arabi responded that they were ignorant of the attribute, not the one described by it.
(Ad-Durr al-Masun, by As-Samin al-Halabi, 1/30)
10 - Ibn Kathir:
Ar-Rahman is more emphatic than Ar-Raheem. This is reflected in the words of Isa (peace be upon him), who said: Ar-Rahman is the Compassionate One in this world and the Hereafter, while Ar-Raheem is the Merciful One in the Hereafter.
(Tafsir Ibn Kathir, 1/124-125)
11 - Ibn Arafah:
Ibn Arafah raised the question: "Why was Ar-Rahman mentioned first, even though it is more emphatic than Ar-Raheem? Shouldn’t the lesser name precede the stronger one?" Two responses are given:
Ar-Rahman is specific to Allah alone, like a proper noun.
Ar-Rahman refers to grander blessings, while Ar-Raheem refers to subtler ones.
(Tafsir Ibn Arafah, 1/27)
12 - Abū al-Suʿūd's said:
"Ar-Rahmān" (the Most Merciful) and Ar-Rahīm are two attributes derived from the verb raḥima (he showed mercy), after making the verb intransitive, placing it in the same category as innate qualities, through shifting it to raḥuma with a ḍammah on the ḥāʾ, as is well known. It has also been said that ar-Rahīm is not a ṣifah mushabbahah (a descriptive adjective) but rather a hyperbolic form, as explicitly mentioned by Sībawayh (the famous grammarian)."
13- Al-Ālūsī's Commentary:
"The prevalent opinion is that Ar-Rahmān and Ar-Rahīm are two descriptive attributes formed to convey emphasis, derived from the verb raḥima (with a kasrah on the ḥāʾ), which was transferred to raḥuma (with a ḍammah), after making it intransitive. This usage is common in the context of praise and blame. Linguistically, raḥmah (mercy) denotes tenderness of the heart, and since such emotions are among the qualities tied to physical temperament, which is impossible for God Almighty, mercy is understood with reference to its outcomes. This is explained either through majāz mursal (metonymy) by mentioning the cause (mercy) and intending the effect (benefit), or through analogy. In this case, Allah’s relationship to the recipients of mercy in conveying goodness to them is likened to the state of a king when he shows tenderness toward his subjects and grants them benevolence. Thus, the words used for the second state are employed for the first without stretching the meaning of the individual components. Alternatively, the comparison can be made using a ṣarīḥah (explicit metaphor) according to Qāḍī Abū Bakr, where iḥsān (benevolence) or its intention is compared to mercy, based on the shared result of benefiting the recipient, and thus the term raḥmah is metaphorically applied, with Ar-Rahmān and Ar-Rahīm derived from it in the manner of the phrase, 'The state speaks for itself.'
Another explanation is through an istāʿārah makniyyah takhīliyyah (implied metaphor), where the concept behind the pronouns referring to Allahy in both Ar-Rahmān and Ar-Rahīm is likened to a king whose heart has softened towards his subjects, with the explicit comparison omitted, and one of its characteristics, mercy, affirmed. It has also been said that raḥmah (mercy) in this context is a ḥaqīqah sharʿiyyah (legal reality), and that Ar-Rahmān conveys a higher degree of mercy than Ar-Rahīm due to the increase in its linguistic structure, which indicates an intensification of meaning. This can be understood quantitatively, where some scholars say, 'O Rahmān of this world,' because His mercy encompasses both the believer and the disbeliever, while Rahīm is reserved for the hereafter, being specific to the believers. Alternatively, it can be understood qualitatively, as some say, 'O Rahmān of both this world and the hereafter,' and 'O Rahīm of this world,' because the blessings of the hereafter are all great, while the blessings of this world include both the significant and the insignificant.
As for the precedence of Ar-Rahmān over Ar-Rahīm, despite the logical progression typically requiring an upward movement, it is due to the precedence of mercy in this world, and also because Ar-Rahmān has become akin to a proper name, given that it is not used to describe anyone other than Him, as its meaning implies the true Benefactor, whose mercy reaches its ultimate extent, and this cannot apply to anyone other than Him.”
Third: Statements from Some Scholars of Aqeedah (Creed) Regarding the Name of Allah "Ar-Raheem"
1- Ibn al-Qayyim said: “The requirement of mercy that brings life to the hearts and souls is far greater than that which brings life to bodies and physical forms. However, those who are veiled only comprehend from this name the portion of animals and livestock, while the people of intellect understand something far beyond that.”
[Madārij al-Sālikīn bayna Manāzil Iyyāka Naʿbudu wa-Iyyāka Nastaʿīn, Ibn Qayyim al-Jawziyyah (d. 751 AH), 1/32].
2- As-Safārīnī said: “The attribute of mercy is an eternal attribute that is part of His Essence and necessitates favor and kindness.”
Shaykh al-Islam Ibn Taymiyyah, may Allah have mercy on him, said in his commentary on the al-ʿAqīdah al-Aṣfahāniyyah: “What the Salaf (pious predecessors) of the Ummah and its leaders agreed upon is that Allah is described by what He has described Himself with, and by what His Messenger described Him with, without distortion or negation, and without asking how or likening Him to His creation.”
[Lawāmiʿ al-Anwār al-Bahiyyah wa-Sawātiʿ al-Asrār al-Athariyyah Sharḥ ad-Durrah al-Muḍiyyah, Shams ad-Dīn as-Safārīnī (d. 1188 AH), 1/221].
3 - Muhammad ibn ʿAbd al-Wahhāb: It is reported from Abu Hurayrah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: “When Allah created creation, He wrote in a book, which is with Him above the Throne: ‘Indeed, My Mercy prevails over My Wrath.’” Narrated by al-Bukhārī. This hadith affirms the Throne, that Allah is above the Throne, and affirms the attributes of mercy and wrath for Allah, the Exalted.
[Uṣūl al-Īmān, Muhammad ibn ʿAbd al-Wahhāb (d. 1206 AH), p. 41].
4- Ibn ʿĪsā, quoting Ibn al-Qayyim, may Allah have mercy on him, said: “As for the combination of ar-Rahmān and ar-Rahīm, it contains a beautiful meaning. Ar-Rahmān indicates the attribute inherent in Allah, and ar-Rahīm indicates its application to the one receiving mercy. It is as if the former signifies the description, and the latter signifies the action. The first denotes that ar-Rahmān is an attribute of His Essence, while the second denotes that He bestows mercy upon His creation, which is an attribute of His action. If you wish to understand this, contemplate His saying: “And He is Merciful to the believers” [Qur’an: 33: 43], “Indeed, He is to them Kind and Merciful” [Qur’an: 9: 117]. The phrase ‘Merciful to’ is never used with ar-Rahmān. This shows that ar-Rahmān refers to the One characterized by mercy, and ar-Rahīm refers to the One who shows mercy by His actions.”
[Tawḍīḥ al-Maqāṣid wa-Taṣḥīḥ al-Qawāʿid Sharḥ Qaṣīdah al-Imām Ibn al-Qayyim, Aḥmad ibn ʿĪsā (d. 1327 AH), 1/14].
5- Ibn Hirrās: “The Ashʿarites and Muʿtazilites denied the attribute of mercy, claiming that it implies weakness and emotional disturbance for the one receiving mercy. This is among the most ignorant of claims, as mercy is typically shown by the strong towards the weak. It does not imply weakness or feebleness, but rather it can accompany absolute might and power. A strong person can show mercy to their young child, to their elderly parents, or to anyone weaker than them. Where is the weakness in that? These are among the most detestable qualities.”
[Sharḥ al-ʿAqīdah al-Wāsiṭiyyah, with Mulḥaq al-Wāsiṭiyyah, Muḥammad ibn Khalīl Harrās (d. 1395 AH), 1/106].
6 - Al-Barrāk, quoting Ibn Ḥajar, may Allah have mercy on him: “Mercy is of two types: a mercy that is an attribute of the Essence, which does not change, and a mercy that is an attribute of action.”
[Taʿlīqāt ash-Shaykh al-Barrāk ʿalā al-Mukhālafāt al-ʿAqīdiyyah fī Fatḥ al-Bārī, ʿAbdur-Raḥmān ibn Nāṣir al-Barrāk, 10/432]
