The teachings of Islam come from two sources, the Quran and the Hadith.  Muslims believe the same angel (Gabriel) that came to prophets Abraham, Moses and Jesus also came to prophet Muhammad (peace be upon them all).  Muslims also believe that God, through the angel Gabriel, revealed the Quran to Muhammad (peace be upon him).  This was done over a period of twenty-three years.  Muslims  consider  the  Quran  to  be  God's  last revelation to mankind. In the Quran, God describes it as a healing for all who choose to follow its teachings. The Quran enlightens and guides over one and a half billion people from  around the world.  One in every five persons is a Muslim.

The Hadith are sayings and practices of prophet Muhammad (peace be upon him).  Muhammad (peace be upon him)  lived during the sixth and seventh centuries.  Muslims accept him as God’s last prophet and  messenger to mankind.  He invited people to the same God that Abraham, Moses and Jesus (peace be upon them) invited people to.  The sayings of  prophet Muhammad (peace be upon him) number in the thousands, and cover a variety of topics.
