Although the date Ja'far conquered Mecca is not known, Ibn Hazm writes that it was during the reign of the Ikhshidids in Egypt. Al-Fasi narrows it down to the years 356-358 AH (967-969), since Ikhshidid influence in the Hejaz waned after the death of Abu al-Misk Kafur. However, he does acknowledge that this is contradicted by some chronicles which indicate that Ja'far had Kafur's name pronounced in the khutbah.[2]
