Abu Bakr ibn Abi Shaybah narrated to us, Ghandar narrated to us, from Shu'bah — and Muhammad ibn al-Muthanna and Ibn Bashshar narrated to us, and the wording is that of Ibn al-Muthanna — they said: Muhammad ibn Ja'far narrated to us, from Shu'bah, from Abu Ishaq, who said: I heard al-Bara' say: The Ansar, when they performed the Hajj and returned, would not enter their houses through their doors, but only from their backs. He said: Then a man from the Ansar came and entered through his door, and it was said to him concerning that, and this verse was revealed: "And righteousness is not that you enter houses from their backs."
