 In 907 or 908 Sebük-eri sent him on a military expedition against Makran, whose ruler, the Ma'danid 'Isa b. Ma'dan, had not paid tribute due to the Saffarids for the last several years.Al-Layth was able to gain the tribute owed, but when he returned Sebük-eri ordered him back to Makran and took his son hostage in an effort to compel him to obey.Instead, al-Layth launched a rebellion in Kerman, which was administered by Sebük-eri, and gained aid from Tahir, but his army abandoned him when Sebük-eri's force approached.
