Surah 106:3
"Let them serve the Lord of this House,"
106.3 – Let them serve the Lord of this House
This is also the only occurrence of the expression “Lord of this House.” At 5.97 the Quran associates “the House” (al-bayt) with the Ka‘ba, believed to be the cube-shaped structure at the center of Muslim worship in Mecca.
