Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that one day the Messenger of Allah (peace and blessings be upon him) delivered a sermon to us. During the sermon, he recited Surah Sad. Then, when he recited the verse of prostration, he descended (from the pulpit) and performed prostration, and we also performed prostration with him. On another occasion, he recited it again, and when he reached the verse of prostration, we prepared to perform prostration. When the Messenger of Allah (peace and blessings be upon him) saw us ready, he said: "Indeed, this is the place of repentance of a prophet (Dawud, peace be upon him). But I saw you ready to perform prostration." Therefore, the Messenger of Allah (peace and blessings be upon him) descended from the pulpit and performed prostration, and we also performed prostration.
