سنن أبي داود

Abdullah ibn as-Sa'ib reported on the authority of his father as-Sa'ib that he used to lead Ibn Abbas (when he become blind) and make him stand in the third corner that was adjacent to the corner (Black Stone) near the entrance of the Ka'bah. Ibn Abbas used to say: Has it been reported to you that the Messenger of Allah (ﷺ) would pray in this place. He would reply: Yes. He then used to stand (there) and pray.
