Narrated to us by Muhammad ibn Ja’far, who said: Narrated to us Shu’bah, from ‘Amr ibn Murrah, who said: I heard Abu Hamzah narrating from Ash-Sharid ibn Suwayd ath-Thaqafi, who said: The Messenger of Allah (ﷺ) passed by me while I was sitting, having placed my left hand behind my back and leaning upon the palm of my hand. He said: "Do you sit in the manner of those upon whom the wrath of Allah has descended?"
