Al-Abbas ibn Ali

Al-'Abbas ibn 'Ali Arabic: ¿¿¿¿¿¿ ¿¿ ¿¿¿¿) (born 4th Sha'ban 26 AH - 10 Muharram 61 AH ; approximately May 15, 647 - October 10, 680) was the son of 'Ali ibn Abi Talib (fourth Rashidun Caliph and first Shi'ah Imam) and Fatimah bint Hizam al-Kilabiyyah (commonly known as: Ummul Banin - Mother of the Sons). Al-'Abbas is particularly revered by Shi'ah Muslims for his loyalty to his half-brother and third Shi'ah Imam, Husayn ibn 'Ali, his respect for the Ahl al-Bayt, and his role in the Battle of Karbala. He was known as the greatest warrior in Arabia and mirrored the strength of his father, 'Ali ibn Abi Talib. After being told by the archangel Gabriel about what would happen to his grandson Husayn at Karbala, Muhammad informed both Fatimah and 'Ali. After the passing away of Fatimah, 'Ali asked his brother 'Aqil to search a wife for him of courageous descent, who would bear him a son that would help Husayn in his hardship. 'Aqil pointed out Fatimah al-Kilabiyyah, who was descended from the honored lineage of Hizam ibn Khalid ibn Rabi'a ibn Amr Kalbi.
