Mount Tur is that mountain in the desert of Sinai where Moses was awarded prophethood. The Scripture penned on unrolled parchment or the written Book (kitabun mastur) here means the Torah. The frequented house (al-bayt al-ma‘mur) means the Kabah. The lofty vaults of the sky or high roof (as-saqf al-marfu‘) means the sky.
