Hazrat Abbas was the son of Hazrat Ali ibne Abi Talib. His mother's name was Fatima Binte Hazam bin Khalid Ibn-e-Rabi'e Ibn-e-Amer Kalbi. She was also known as 'Ummul Baneen'. She belonged to the clan of Banu Kilah, which was one the noblest families amongst the Hashimites and famous for the bravery and valour of its warriors.
Some years after the martyrdom of Fatema Zehra (S.A.), Imam Ali (A.S.) asked his brother Aqil to offer the marriage proposal to a woman from a brave progeny. Being so knowledgeable in this regard, Aqil wooed Fatima Binte Hazam (Ummul Baneen) for Imam and they got married.
Fatima Binte Hazam was an accomplished and cultured lady, and bore Hazrat Ali's four sons, Abbas, Abdulla, Ja'far and Usman. The meaning of 'Ummul Baneen' is 'Mother of Sons'. All of her sons were martyred along with Imam Hussain. After their martyrdom, she requested people not to call her 'Ummul Baneen' ever again.
The day she entered the household of Hazrat Ali, she made it very plain to Imam Hasan and Imam Hussain that she considered herself their slave, and she hoped and prayed that they would accept her as one. Her respect and affection for there was soon reciprocated by the two brothers, and even after her children were born, Imam Hasan and Imam Hussain occupied a foremost place in her heart.
Fatima Binte Hazam had such sincerity toward the Holy Prophet's progeny that she loved Imam Hussain (A.S.) more than her own children. A feeling which was from the bottom of her heart. It was to the extent that when she received the news stating the martyrdom of her four children, she said: "Tell me about Hussain (A.S.)" and when she received the news of Imam Hussain (A.S.)'s martyrdom she said: "All of the arteries of my heart are torn. May all of my children and what ever that exists under this azure heaven be sacrificed for the sake of Imam Hussain (A.S.).
One of the bravest of the Holy Prophet's followers Ja'far Tayyar, the brother of Hazrat Ali. In the battle of Muta, Ja'far Tayyar carried the Banner of Islam and in that battle he was out-numbered by the enemies and killed. When the news reached the Holy Prophet he cried and prayed for Ja'far's soul and the angel Gabriel came down and consoled (the Prophet), saying "Ja'far was a brave and loyal soldier. God has given him everlasting life, and in place of two arms which were cut off in the battle, the Lord has given him a pair of wings".
Hazrat Ali, who was sitting near the Holy Prophet at that time, said, "Please pray to God that I should die fighting for the cause of Islam and become a martyr." But the Holy Prophet said, "0 Ali, your death has already been decreed. You shall die in the mosque during your prayers, but the Almighty will give you a son who will die in the battle on Ashoora day". From that time Ali eagerly awaited the birth of that son.
(This prophecy was made in the year 8 A.H. when Imam Hasan was 5 years old and Imam Hussain was 4.)
Na Zarurat Thi Talwaar Ki Na Aur Kisi Hathiyar Ki
Sirf Ek Dua Thi Karbala Main Alamdaar Ki
Fakat Mil Jaye Ijazat Aqa Hussain Sai
To Yaad DilaDunga Jung Haider-e-Karrar Ki
