The only significant distinction between the Islamic waqf and English trust was "the express or implied reversion of the waqf to charitable purposes when its specific object has ceased to exist",[9] though this difference only applied to the waqf ahli (Islamic family trust) rather than the waqf khairi (devoted to a charitable purpose from its inception). Another difference was the English vesting of "legal estate" over the trust property in the trustee, though the "trustee was still bound to administer that property for the benefit of the beneficiaries." In this sense, the "role of the English trustee therefore does not differ significantly from that of the mutawalli."[10]
