They reigned together until (c. 6 January 1255), when they were deposed by the emir al-Mubariz Ibn Birtas on behalf of al-Muzaffar of Yemen.
Idris and Abu Numayy retook Mecca two months later, four nights 6 March 1255.
In 1256 Idris was briefly deposed by Abu Numayy when he left Mecca to visit his brother Rajih.
Abu Numayy wrote to al-Zahir Baybars of Egypt, explaining that he had witnessed in Idris an inclination towards al-Muzaffar Yusuf of Yemen and his state, due to which he had expelled his uncle.
That would place Idris's death in Rabi II or Jumada I (sometime c. 26 November – c. 25 December).
