The sons of Abraham

Moses was a descendant of Abraham.  He gave the world the Torah, which he said was based on revelations given to him by God.  Judaism is based on the teachings contained in this book.

Muhammad was a descendant of Abraham.  He gave the world the Koran, which he said was based on revelations given to him by God.  Islam is based on the teachings contained in this book.

The similarities between these two aren’t just a coincidence.
