Hadith Qudsi 103
103) Narrated Abu Huraira : When this verse was revealed to Allah's Messenger "To Allah belongs whatever is in the heavens and whatever is in the earth and whether you disclose what is in your minds or conceal it, Allah will reckon you according to it. Then He will forgive whom He pleases and chastise whom He likes as Allah is All-Omnipotent over every thing." The narrator said: The Companions of Allah's Messenger felt it hard. They came to him, sat down on their knees and said: 0 Messenger of Allah, we have been assigned with some duties (tasks) which we have capability to perform such as: prayer (SaUit), fasting (Saum), fighting in Allah's way (lihad), and charity (Zakat). Now this (the above mentioned verse) was revealed to you and it is beyond our power to live up to. Then Allah's Messenger said: Do you intend to say what the people of the two Scriptures (the Jews and Christians) had said before you: "We hear and disobey". Rather you should say: "We hear, obey and seek your forgiveness, our Lord! And to You is the return". When the people recited it, their tongues became subdued with it. Then Allah revealed: "The Messenger believes in what is sent down to him from His Lord, and so do the believers (following him). Each one believes in Allah and His angels and His Books and His Messengers, saying: We differentiate not between any of His Messengers; and they say: We hear and seek your forgiveness, our Lord! And to You is the return". When they (the Companions) said the same, Allah abrogated this verse and Allah the All-Great, revealed a new one replacing it: "Allah burdens not a soul beyond its capacity. It gets every good that it earns and it suffers every ill that it earns. Our Lord! Punish us not, if we forget or make a mistake". (When the Companions repeated the same words) Allah said: Yes: (The Companions further repeated the words as revealed to Prophet Muhammad Our Lord! Do not lay on us a burden as that you had laid on those before us. Allah said: Yes. (The Companions further repeated) Our Lord! impose not on us (burdens) which we have no strength to bear. Allah said: Yes. (The Companions further repeated) And pardon us and provide us protection; and have Mercy on us. You are our Patron, so please grant us victory over the disbelieving people". Allah said: Yes. (2:285,6)
(This Hadith is sound and reported by Muslim).
The people of the Torah and Bible used to say to their Prophets (we hear and disobey). Unlike them the Companions of Prophet Muhammad were guided by him to say: "We hear and will obey, seek your forgiveness 0 Lord and to You is our return", so a true Muslim should be obedient to the commands of the Qur' an and traditions of Prophet Muhammad
