And when We made the House (at Makka) a resort for mankind and sanctuary, (saying): Take as your place of worship the place where Abraham stood (to pray). And We imposed a duty upon Abraham and Ishmael, (saying): Purify My house for those who go around and those who meditate therein and those who bow down and prostrate themselves (in worship).
Surah Al-Baqara(2:125)
