CAIRO — After months of fierce debate over the place of Islam in government, the assembly drafting a new constitution for Egypt has settled on a compromise that opens the door to more religion in governance but mainly guarantees that the issue will continue to roil politics, the Parliament and the courts for many years to come.

The compromise would insert religion more deeply into the legislative and judicial process by elaborating new guidelines to interpret “the principles of Islamic law” that the old Constitution had recognized, at least nominally, as the main source of Egyptian legislation.
