Khalaf ibn Mula'ib

Sayf al-Dawla Khalaf ibn Mulāʿib al-Ashhabī al-Kilābī (Arabic: سيف الدولة خلف بن ملاعب الأشهبي الكلابي; died 3 February 1106) was the emir of Homs and Apamea between 1082 and 1090.

Muslim installed Khalaf in Homs to serve as buffer between his northern Syrian domain and his Seljuk enemies based in Damascus.

[4] Khalaf is credited in an inscription found in the Mosque of Salamiyah for repairing a mashhad (mausoleum) for one of the "hidden" Isma'ili imams Abd Allah in 1088.

The latter was staying in Apamea at the time and arranged for a hole to be made in the city walls, allowing the entry of the Assassins.

After the city's capture, Tancred gave fiefs in Apamea's vicinity to Musbih and other surviving sons of Khalaf.
