Chapter 16: The Book of Pilgrimage
Salim narrated on the authority of his father (Allah be pleased with him) that 'Umar b. al-Khattib (Allah be pleased with him) kissed (the Black Stone) and then said: By Allah, I know that you are a stone and if I were not to see Allah' s Messenger (ﷺ) kissing you, I would not have kissed you. Harun said in his narration: A hadith like this has been transmitted to me by Zaid b. Aslam on the authority of his father Aslam.
