Imam Ali bin Husain (A.S), more known by his title Zainul Abidin than his actual name, is fourth Imam from the progeny of the Prophet Hazrat Muhammed (S.A.W.W). Like his father Imam Husain (A.S), his uncle Imam Hassan (A.S) and his grandfather Imam Ali (A.S) and the Prophet (S.A.W.W), he was a Masoom (He did not commit any mistake or sins).
He was born on 5th Shaban (or on 15th Jamadi-ul-Awaal) 38 A.H. (658 A.D) in Medina (some historians say he was born in Kufa). His father was Hazrat Imam Husain (A.S) and his mother was Hazrat Sheherbanu. She was a princess from Iran. She was the daughter of Yazd gard II, the last king of Pre-Islamic Iran. Thus he was called “Ibn Al-Khiyaratyn”. or the son of the best two meaning: The Quraysh from the Arabs and the Persians from non-Arabs.
The Muslims, at the time of Umar Khattab, captured Iran in 21 A.H. The ruler, however, was able to run away from Muslims; later he was killed. Several years later his two daughter’s, Sheherbanu and Gayhanbanu were brought as prisoners-of-war at the time when Imam Ali (A.S) was the Caliph of the Muslims. They were sent to Imam Ali (A.S) by his governor, Haris bin Jabir Joafi.
Imam Ali (A.S) freed the two sisters. The elder one Sheherbanu (who was also known as Shahzanan, Sulafa, Ghazala and Sheherbanuya) was given in marriage to Imam Husain (A.S). The younger sister was given in marriage to Muhammed bin Abubakr. Sheherbanu gave birth to Imam Zainul Abidin (A. S) where as Gayhanban gave the birth to Kassim, whose daughter was later married to Imam Mohammed Baqr (A.S).
After her marriage to Imam Husain (A.S), she became very pious. She was regularly praying and g Allah for having brought her to a house in which mercy of Allah was coming every second.
It is reported that once a maid in her house showed pity to Sheherbanu saying that it must have been very hard for her to live in the house of Imam Husain (A.S), she having first lived the life of princess of Persia.
Sheherbanu replied, “You should never talk like that for you do not know where I was and where I am now. I was in the Hell fire and I came to Paradise. I left the house of fire worshippers and came to the house of the worshippers of one Allah...”.
Sheherbanu died a few days after giving birth to Imam Zainul Abidin (A.S). She was not present in Kerbala. Imam Zainul Abidin (A.S) was taken care off, as a child, by a maid whom he came to love and respect like his own mother.
