I am kissing you, whereas I know that you are a stone, but I saw Allah's Messenger (ﷺ) kissing you (that Is why I kiss you).
Sahih Muslim Book 15, Hadith 274
← Previous Hadith 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.

Sahih Muslim Book 15, Hadith 273 Next Hadith → I saw the bald one, i. e. 'Umar b. Khattib (Allah be pleased with him). kissing the Stone and saying: By Allah. I am kissing with full consciousness of the fact that you are a stone and that you can neither do any harm nor good; and if I had not seen Allah's Messenger (ﷺ) kissing you. I would not have kissed you. The rest of the hadith is the same.
