There are many beautiful verses in the #Quran describing the sanctity of the Kaaba and the purpose of its building.

“And when we assigned to Abraham the place of the House: ‘Do not associate with Me anything, and purify My House for those who circumambulate it, who stand in prayer, and who bow, and prostrate themselves (all in prayer).’  And proclaim the Pilgrimage {Hajj} among people, and they shall come to you on foot, and on every lean camel.  They shall come to you from every deep and distant mountain highways.” {Q22:26}
