Ali ibn Husayn (Arabic: علي بن الحسين‎‎) known as Zayn al-Abidin (the adornment of the worshippers) and Imam al-Sajjad (The Prostrating Imam), was the fourth Shia Imam, after his father Husayn, his uncle Hasan, and his grandfather Ali. Ali ibn Husayn survived the Battle of Karbala and was taken to the caliph in Damascus. Eventually, he was allowed to return to Medina, where he led a secluded life with a few intimate companions. Imam Sajjad's life and statements were entirely devoted to asceticism and religious teachings, mostly in the form of invocations and supplications. His famous supplications are known as Al-Sahifa al-Sajjadiyya.

Ali ibn al-Husayn was born in Medina, modern-day Saudi Arabia, in the year 38/658–9. He may have been too young to have remembered his grandfather Ali; he was raised in the presence of his uncle Hasan and his father Husayn, Prophet Muhammad’s grandchildren. It is said that Ali ibn al-Husayn was related through his mother Shahrbanu, the daughter of Yazdegerd, to the last Sassanian King of Persia. Ali ibn al-Husayn was known as Ibn al-Khiyaratayn, the "son of the best two (the Quraysh among the Arabs and the Persians among the non-Arabs)". According to some accounts, Ali ibn al-Husayn's mother was taken as a captive to Medina during the caliphate of Umar, who wanted to sell her. Ali ibn Abi Talib instead suggested allowing her to choose a husband from among the Muslims and paying her mahr from the public treasury. Umar agreed; she chose Ali’s son Husayn. She is said to have died shortly after giving birth to her only son Ali.
