In the Qur’an God says,
“The Messenger firmly believes in what has been revealed to him from his Lord, and so do the believers. They all believe in Allah, His angels, His books, and His messengers [and proclaim], “We make no distinction between any one of His Messengers.”
[Qur’an 2:285]
In Islam, for one to be a Muslim, he HAS to believe in all the Prophets. That includes Prophets Adam, Noah, Abraham, Moses, Jesus, and the last one, Muhammad, peace and blessings be upon them all. To be a true Muslim, you MUST accept that they were chosen by God to guide their people and are great role models.
A Muslim cannot be selective. One cannot say, “I like Prophet Muhammad, but I don’t like Prophets Moses and Jesus.” To dislike them is to say God chose a bad person. To deny them is to deny what God said in the Qur’an.
Thus, the question arises – why do Christians and Jews believe in so many prophets, but deny one or two of them? What in their creeds have allowed them to be selective? If a person has all the proofs of prophethood, isn’t denying him denying God’s message? After all, when Prophet Muhammad (ﷺ) proclaimed the message to the Christians and Jews of his time, several accepted, including the most knowledgeable Jewish scholar of Madinah, Abdullah ibn Salam رَضِيَ ٱللَّٰهُ عَنْهُ. To this day, many who have studied their religions and were humble in finding the truth regard of what that might be, have accepted Islam.
