Abbas ibn Ali, son of Imam Ali
Al-Abbas ibn Ali ibn Abi Talib (Arabic: ٱلْعَبَّاس ٱبْن عَلِيّ ٱبْن أَبِي طَالِب, romanized: al-ʿAbbās ibn ʿAlīy ibn ʾAbī Ṭālib; born 15 May 647 – 10 October 680), also known as Abu al-Fadhl (Arabic: أَبُو ٱلْفَضْل) and Qamar Bani Hashim (Arabic: قَمَر بَنِي هَاشِم, lit. 'Moon of Banu Hashim'), was a son of Ali (the fourth Rashidun caliph) and Fatima bint Hizam, commonly known as Umm al-Banin (Arabic: أُمّ ٱلْبَنِين, lit. 'Mother of the Sons').

Abbas is highly revered in Islam for his loyalty to his brother Husayn ibn Ali and his role in the Battle of Karbala in which he was the standard-bearer for the Ahl al-Bayt. Abbas is buried in the Al-Abbas Shrine in Karbala, Iraq, where he was killed during the Battle of Karbala on the day of Ashura. He was praised for his handsome looks and was also well known in the Arab community for his courage, bravery, strength and ferocity as a warrior. Ibn Manzur narrates in his al-Ayn that Al-Abbas was the lion that other lions feared as a testament to his accolades as a warrior. Sheikh at-Turaihi describes Abbas's appearance as resembling an unshakable mountain, with his heart firmly rooted, due to his qualities as a unique horseman and a fearless hero.
