Sunan Ibn Majah, 871

Rapporté par ‘Ali bin Shaiban, qui faisait partie d’une délégation auprès du Prophète (ﷺ) : Nous sommes partis jusqu’à arriver auprès du Messager d’Allah (ﷺ), nous lui avons prêté allégeance et avons prié derrière lui. Il a regardé du coin de l’œil un homme qui ne redressait pas sa colonne vertébrale en s’inclinant et en se prosternant. Quand le Prophète (ﷺ) a terminé la prière, il a dit : “Ô musulmans, il n’y a pas de prière pour celui qui ne redresse pas sa colonne vertébrale en s’inclinant et en se prosternant.”

It was narrated that ‘Ali bin Shaiban who was part of a delegation (to the Prophet (ﷺ)) said:“We set out until we came to the Messenger of Allah (ﷺ), and we gave him our oath of allegiance and performed prayer behind him. He glanced out of the corner of his eye at a man who was not settling his spine when he bowed and prostrated. When the Prophet (ﷺ) finished the prayer, he said: ‘O Muslims, there is no prayer for the one who does not settle his spine when bowing and prostrating.’”
