‘Abis b Rabi'a said he saw ‘Umar kissing the stone and saying, “I know for sure that you are a stone which can neither benefit nor injure, and had I not seen God’s messenger kissing you I would not have kissed you.”
Umm Salama said that she complained to God’s messenger of being ill, and he told her to perform the circumambulation behind the people riding. She did so, and God’s messenger was praying towards the side of the House and reciting, “By at-Tur and a Book inscribed.”( Qur’an, 52. The text here has bit-Tur, whereas the Qur’an has wat-Tur. Bukhari has wat- Tur in Hajj, 64, but he has bit-Tur ,in Salat, 78, Hajj, 74, and Tafsir Surat at-Tur, 1).
Abu Huraira reported the Prophet as saying, “Seventy angels have been put in charge of it (i.e. the Yamani corner), so if anyone says, ‘O God, I ask Thee for pardon and wellbeing in this world and the next; our Lord, bring us a blessing in this world and a blessing in the next, and guard us from the punishment of hell’, they will say Amen.”
Ibn ‘Umar said, “We did not give up touching these two corners, the Yamani and the stone, whether it was difficult or easy, since I saw God’s messenger touch them." In a version by both of them Nafi’ said he saw Ibn ‘Umar touching the stone with his hand, after which he kissed his hand. He said, “I have not given it up since I saw God's messenger doing it."
