3.Miracles and Wonders with which Allah (Mighty & Majestic) Supported His Prophets and Messengers:
Allah (Mighty & Majestic) sent His prophets and messengers, supported by miracles and wonders as testament to their prophethood, message, the truth of their call, and all the news they came with, especially since their call conformed completely to pure, unspoiled human nature and straightforward, honest reason.
We have presented previously some aspects of the tangible miracles of Allah's Messenger, Muhammad (pbuh).
Thus, all people must believe in each of Allah's prophets and messengers when it becomes clear that their call—which agrees with pure human nature and straightforward, honest human reason—is true, and when supporting testimony for the truth of their prophethood and message appears in the form of miracles and wonders, sent by Allah (Mighty & Majestic) to support them with that which none other than the prophets and messengers are capable of producing.
As such, rejecting or opposing any of the prophets or messengers is, in fact, rejection of all the prophets and messengers. Indeed, it is rebellion against Allah (Mighty & Majestic) Who sent them.
Just as those who believe in a messenger are obliged to believe in all the messengers, anyone who disbelieves in one of them has necessarily disbelieved in them all. In the Words of the Most High,
Verily, those who disbelieve in Allah and His Messengers and wish to make a distinction between Allah and His Messengers, saying, "We believe in some, but reject others," wishing to adopt a way in between, * They are, in truth, disbelievers. And We have prepared for the disbelievers a humiliating torment. * And those who believe in Allah and His Messengers and make no distinction between any of them, We shall give them their rewards, and Allah is Ever Oft-Forgiving, Most Merciful.
[Al-Nisaa' 4: 150-152]
Likewise, we would like to make it clear that every time a prophet has reached a people, they became his nation, and they were obliged to obey him. For example:
If someone believed in the Prophet of Allah, Moses (peace be upon him), because of what he learned about the truth of his call, which agrees with pure human nature and sound reason, and he followed the law with which Moses (pbuh) came, and then this person met the Prophet of Allah, Jesus (peace be upon him), and became convinced of his prophethood and message, could this person, who believed in Moses (pbuh) and followed the law with which he came, not follow the Prophet of Allah, Jesus (pbuh), and the law with which he came, claiming that he was from the nation of Moses (pbuh) and not from the nation of Jesus (pbuh)?
Of course not, since that person would have reached the Prophet of Allah, Jesus (pbuh). Thus, he would become of his nation and he would be obliged to abide by the law with which he came, not the law with which Moses (pbuh) came.
Therefore, everyone who reaches the Messenger of Allah, Muhammad (pbuh), has become of his nation, and he becomes obliged to follow him (pbuh), and abide by the law with which he came, whether he was a Jew, a Christian, or otherwise.
The truth is that everyone who follows the Prophet of Allah, Moses (pbuh) or the Prophet of Allah, Jesus (pbuh), correctly, would be led by this following to believe and have faith in the prophethood and message of the Prophet Muhammad (pbuh) and to follow him. That is because both the Torah and the Gospels, as well as other divine scriptures brought good tidings and news of this prophet, the Seal of the Prophets and Messengers, Muhammad (peace and blessing be upon him). We shall, by the Will of Allah Almighty, mention some of these prophecies in good time.
Thus, authentic scriptural reference and straightforward logic both lead to belief in the Final Message—that of Muhammad, may the peace and blessing of Allah be upon him.
