"The House of Islam" or "Land of Islam." According to the Raddu 'l Mukhtar, vol. iii. p. 391, it is a country in which the edicts of Islam are fully promulgated.

In a state brought under Muslim rule, all those who do not embrace the faith are placed under certain disabilities. They can worship God according to their own customs provided they are not idolaters; but it must be done without any ostentation and whilst churches and synagogues may be repaired, no new place of worship can be erected. "The construction of churches and synagogues in Muslim territory is unlawful, this being forbidden in the Traditions; but if the places of worship belonging to Jews, or Christians, be destroyed, or fall into decay, they are at liberty to repair them because buildings cannot endure forever."

Idol temples must be destroyed, and idolatry suppressed by force in all countries ruled according to strict Muslim law. (Hidiyah, vol. ii, p. 219)
