Our Master Shith
Adam (may peace be upon him) lived as a Muslim, as did Hawwa'.
They worshipped Allah, the Exalted, and did not worship other than Him. Their children lived as Muslims. After Adam died, Shith received the Revelation of prophethood. Shith was Adam's son. All the humans were Muslim throughout Shith's life.
After Shith died, another Prophet was revealed whose name was ldris. He lived a long time teaching the people the Religion of Islam.
