Mansur was dismissed in 1579 and replaced by his son Muhammad, who was imprisoned by the authorities in 1584 for alleged involvement in a looting raid against an Istanbul-bound caravan. He was restored to Keserwan in 1585 and was given tax collection authority over the rural districts of Tripoli Eyalet; this brought him into conflict with the Sayfa clan, the Assafs' erstwhile Turkmen clients, one of whose members, Yusuf Pasha Sayfa, was governor of Tripoli. The Assaf realm dissipated in 1591 when Muhammad was killed while attempting to collect taxes from the Sayfas in Akkar.
