It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that one day the Messenger of Allah (peace and blessings be upon him) addressed us and recited Surah Sad. When he reached the (verse of) prostration, he (peace and blessings be upon him) came down and prostrated, and we also prostrated with him. Then he recited it once again, and when he reached the (verse of) prostration, we got ready to prostrate. When he (peace and blessings be upon him) saw us (ready), he said: "This is only the repentance of a Prophet, but I see that you have got ready to prostrate." So he (peace and blessings be upon him) came down and prostrated, and we also prostrated. This hadith is sahih (authentic) on the condition of the two Shaykhs, but they did not record it, while the prostration of Surah Sad has been recorded by Imam Bukhari. The purpose of bringing it here in the Book of Friday is that when the imam recites a verse of prostration on the pulpit on Friday, the sunnah is that he comes down and prostrates.

Sayyiduna Jarir bin Abdullah (may Allah be pleased with him) narrates: When I drew near to the city of the Messenger of Allah (peace and blessings be upon him) (Madinah), I made my mount kneel, opened my baggage, and put on my (best) garment. Then I entered the mosque while the Messenger of Allah (peace and blessings be upon him) was delivering the sermon. He (peace and blessings be upon him) greeted me with salam, and the people began to stare at me. I asked the man sitting next to me: O servant of Allah! Has the Messenger of Allah (peace and blessings be upon him) mentioned anything about me? He said: Yes, he (peace and blessings be upon him) mentioned you in the best of terms and said: "There will enter upon you from this door - or from this mountain pass - one of the best people of Yemen, on whose face there is a radiance like that of an angel." So I praised Allah for this favour. This hadith is sahih (authentic) on the condition of the two Shaykhs, and it is a foundation for the imam being able to speak during the sermon about matters that arise.
