The 3rd of Rajab marks the date of martyrdom of the 10th Imam in the progeny of Prophet Muhammad (S.A.W.W.), Imam Ali Naqi (A.S.). He is the son of Muhammad-e-Taqi(A.S.), son of Ali-e-Raza (A.S.), son of Musa-e-Kazim(A.S.), son of Jafar-e-Sadiq (A.S.), son of Muhammad-e-Baqar (A.S.), son of Ali Zain-ul-Abideen (A.S.), son of Imam Husain (A.S.) who is the brother of Hasan (A.S.) and son of Ali (A.S.) and Fatima (S.A.), the son-in-law and daughter of the Prophet (S.A.W.W.), respectively.

He was martyred during imprisonment by Mo’taz (L.A.) of the Abassids (L.A.), also known as the Yazid of the Abassids for his inhumane treatment of the Prophet’s family (S.A.W.W.).

Imam Ali Naqi (A.S.) was buried in Samarrah, Iraq in his home. His shrine is popularly known as the Mosque with the Golden Dome and the Al-Askariya Mosque, and houses the resting places of his son Imam Hasan Askari (A.S.), sister Hakimah Khatoon (S.A.), and Nargis Khatoon (S.A.), wife of Imam Hasan Askari (A.S.), also. In addition to this, it is hailed as the place where Imam Mehdi (A.S.) disappeared from the eyes of the world.

The shrine was bombed two years ago which resulted in the dome getting martyred. Then last year, terrorists bombed it again to martyr the standing minarets also.
