[2] In 1342, Isma'il married a black slave girl named Ittifaq and had a son (unnamed in sources) with her that year.
The third son, an-Nasir Ahmad, came to power in January 1342, but was a highly seclusive leader who ruled from the isolated desert fortress of al-Karak, beginning in May.
[3] The final siege, commanded by Emir Sanjar al-Jawli,[4] succeeded in early July 1344, and an-Nasir Ahmad was captured and soon murdered on the secret orders of Isma'il, who hired a mercenary to accomplish the task.
However, according to historian Peter Malcolm Holt, Isma'il' "made little impression on the course of events in his short reign".
[7] Isma'il was praised by the Mamluk-era historian Ibrahim al-Qaysarani as the "renewer" (mujaddid) of the Islamic faith in the sultanate during the closing of the first 100 years of Mamluk rule.
