Salim narrated on the authority of his father (RA) that 'Umar bin al-Khattib (RA) 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 bin Aslam on the authority of his father Aslam.
