Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), in the explanation of the verse "Like a niche" [Surah al-Nur: 35], said: "It refers to the breast of Muhammad (peace and blessings be upon him); the glass refers to his heart; and the lamp refers to the light that is in his heart. 'Lit from a blessed tree': the tree refers to Ibrahim (peace be upon him). 'An olive tree, neither of the east nor of the west': that is, neither Jewish nor Christian." Then he recited this verse: "Ibrahim was neither a Jew nor a Christian, but he was an upright Muslim, and he was not of the polytheists" [Surah Al Imran: 67].
