Abū ʿAlī Ḥasan, or ʿAlī, surnamed Al-Hādī was the 20th Ismaili Nizari Imam. Born in Cairo, he was about 17 years old when his predecessor, Imam al-Mustansir, died, and 20 years old during the assumption of his Imamate in 490 AH/1097 CE. Henceforward, the seat of Ismaili Imamate was transferred from Egypt to Persia owing to the division among the Ismailis, where Hasan bin Sabbah had founded the Nizari Ismaili state.
