Ali was born on the 13th of Rajab of the 30th year of the Elephant (A.D. 600). His cousin, Muhammad, was now 30 years old. Ali’s parents were Abu Talib ibn Abdul Muttalib, and Fatima, the daughter of Asad, both of the clan of Hashim.
Ali was born inside the Kaaba in Makkah. The great historian, Masoodi, the Herodotus of the Arabs, writes on page 76 of Volume II of his book, Murooj-udh-Dhahab (The Golden Meadows), that one of the greatest distinctions that Ali enjoyed was that he was born in the House of Allah.Some of the other authorities who have affirmed Ali’s birth in the Kaaba, are:
