3) Muhammad
Muhammad was one of the several prophets of God or "Allah" (CA 570 – 632) and is the most recent one. He is regarded as the founder of Islam since he was the one who received God's messages in the forms of divine revelation given by the Angel Gabriel in the Mecca and Medina cities, starting at the age of 40 years old. Muhammad wrote all of these revelations down, which are what now is the Holy Qur'an, a book whereby Islam is based.
