Our Holy Prophet was born on 12-17 Rabi-al-Awal, 01 Amulfil (530 S). As his Father, Abdullah (A) died before his birth, he was taken care by Abdul-Muttalib (A) and after Abdul-Muttalib's (A) death, Abu Talib (A) took care of Mohammed (PBUH). When Mohammed (PBUH) was doing prayers in a cave (known as "Hira"), Gibreel visited the cave and Mohammed (PBUH) received his first revelation from Allah.
