Mujir al-Din al-ʿUlaymi described an earthquake that struck Jerusalem and damaged the Al Aqsa Mosque, which he dated to A.H. 130 (11 September 747 – 30 August 748 CE). His account includes three instances of eyewitness testimony transmitted through a chain of witnesses ( isnād ), describing an earthquake that struck at night. One witness reported two earlier daytime foreshocks, possibly in the afternoon. Another witness described the main shock as occurring on a black and cold night, full of rain and wind, yet also claimed that the quake breached the roof of the Al Aqsa Mosque so that the stars appeared — an apparent discrepancy, since stars would not have been visible on a stormy night. Otherwise, the testimonies are largely consistent.

In another passage, Mujir al-Din recorded that an earthquake in A.H. 130 damaged the Al Aqsa Mosque, prompting repairs during the reign of Caliph al-Mansur (r. 754–775 CE). A subsequent, undated earthquake destroyed the repaired structure, leading to a second reconstruction to new dimensions under Caliph al-Mahdi (r. 775–785 CE).
