One might well ask:
How many prophets has God sent to humanity? We are only sure of what is clearly mentioned in the Quran, that God has sent a messenger to every nation. That is because it is one of God’s principles that He will never call a people to account unless He has made clear to them what to do and what not to do. The Quran mentions the names of 25 prophets and indicates that there have been others who were not mentioned to Prophet Muhammad, may the mercy and blessings of God be upon him. These 25 include Noah, Abraham, Moses, Jesus, and Muhammad (may God praise them all). These five are the greatest among God’s messengers. They are called ‘the resolute’ prophets.

All the prophets came from the same One God, for the same purpose: to lead mankind to God. Hence, belief in them all is essential and logical; accepting some and rejecting others has to be based on misconceptions of the prophet’s role or on a racial bias. The Muslims are the only people in the world who consider the belief in all the prophets an article of faith.
