Abu Ghassan al-Misma'i narrated to me: Mu'adh — meaning Ibn Hisham — narrated to us: my father narrated to me. (Another chain:) Muhammad ibn al-Muthanna narrated to us: Ibn Abi 'Adiyy narrated to us, from Sa'id — both of them from Qatadah, from Anas, that the Prophet of Allah, peace and blessings be upon him, said: "Complete the bowing and prostration. By Allah, I indeed see you from behind my back when you bow and when you prostrate." In the narration of Sa'id: "when you bowed and when you prostrated."
