I speak from the traditional knowledge in Islam.
There have been 124 000 prophets, peace be upon them all. The first was Adam (peace be upon him), the last was Muhammad (peace be upon him and his family). Muhammad is the Seal of the prophets, the last of them and the best of them. Muhammad was born in 570 and died in 632.
Because Muhammad was the last prophet, the Seal of the prophets, God supported him with saints. These saints of Islam came at each century, from the 7th century (after Muhammad and his Companions) to today in the 21st century. There are 124 000 saints of Islam. These saints are in contact with God and with His prophet Muhammad. Muslims are forbidden to take up the religion on their own, they must seek these saints and take the religion from them. These saints are the ones who know the meanings of the Qur'an and the Hadiths (the sayings of Muhammad). It is forbidden to read the Qur'an and the Hadiths and to have one own's understanding of it. People are under the obligation to refer to the saints of Islam for the interpretation of the Qur'an and the Hadiths.
