When authority (1) passed to ʿAbd al-Muʾmin ibn ʿAlī, he treated the subjects kindly, and an exemplary conduct (2) became manifest from him. The people loved him; his dominions broadened, his armies and populace multiplied, and he declared open enmity toward Ibn (3) Tāshfīn, the ruler of Marrakesh.
