Musannaf Ibn Abi Shaybah

Hazrat Aamir narrates that the person who read that document, which was found either from the walls of the roof of the Ka'bah or from beneath Maqam Ibrahim, related to me (it was written in it): I am the God of the Ka'bah, I have built it before seven kingdoms, I have placed blessings in the food and drink (meat and water) for its inhabitants, and I have made the sustenance of its inhabitants from three ways, and the very first to consider its sanctity as permissible are its own people.
