Abu Qatada reported
The Messenger of Allah (ﷺ) led us in prayer and recited in the first two rak'ahs of the noon and afternoon prayers Surat al-Fitiha and two (other) surahs. And he would sometimes recite loud enough for us the verses. He would prolong the first rak'ah more than the second. And he acted similarly in the morning prayer.
Abu Qatada reported it on the authority of his father
The Messenger of Allah (ﷺ) would recite in the first two rak'ahs of the noon and afternoon prayers the opening chapter of the Book and another surah. He would sometimes recite loud enough to make audible to us the verse and would recite in the last two rak'ahs Surat al-Faitiha (only).
Abu Sa'id al-Khudri reported
We used to estimate how long Allah's Messenger (ﷺ) stood in the noon and afternoon prayers, and we estimated hat he stood in the first two rak'ahs of the noon prayer as long as it takes to recite Alif Lam Mim, Tanzil, i. e. as-Sajda. We estimated that he stood half that time in the last two rak'ahs; that he stood in the first two of the afternoon as long as he did in the last two at noon; and in the last two of the afternoon prayer about half that time. Abu Bakr in his narration has made no mention of Alif Lam Mim, Tanzil, but said: As long as it takes to recite thirty verses.
Abu Sa'id al-Khudri reported
The Apostle of Allah (ﷺ) used to recite in every rak'ah of the first two rak'ahs of the noon prayer about thirty verses and in the last two about fifteen verses or half (of the first rak'ah) and in every rak'ah of the 'Asr prayer of the first two rak'ahs about fifteen verses and in the last two verses half (of the first ones).
Jabir b. Samura reported
The people of Kufa complained to Umar b. Khattab about Sa'd and they made a mention of his prayer. 'Umar sent for him. He came to him. He ('Umar) told him that the people had found fault with his prayer. He said: I lead them in prayer in accorance with the prayer of the Messenger of Allah (ﷺ). I make no decrease in it. I make them stand for a longer time in the first two (rak'ahs) and shorten it in the last two. Upon this 'Umar remarked: This is what I deemed of thee, O Abu Ishaq.
This hadith his been narrated by 'Abu al-Malik with the same chain of transmitters.
Jabir b. Samura reported
'Umar said to Sa'd: They complain against you in every matter, even in prayer. He (Sa'd) said: I prolong (standing) in the first two (rak'ahs) and shorten it in the last two, and I make no negligence in following the prayer of the Messenger of Allah (ﷺ). He ('Umar) remarked: This is what is expected of you, or, that is what I deemed of you.
This hadith is narrated by Jabir b. Samura but with the addition of these words
" (Sa'd said): These bedouins presume to teach me prayer."
Abu Sa'id al-Khudri reported
The noon prayer would start and one would go to al-Baqi' and after having relieved himself he would perform ablution and then come, while the Messenger of Allah (ﷺ) would be in the first rak'ah, because he would prolong it so much.
Qaz'a reported
I came to Abu Sa'id al-Khudri and he was surrounded by people. When the people departed from him I said: I am not going to ask you what these people have been asking you. I want to ask you about the prayer of the Messenger of Allah (ﷺ). He (Abu Sa'id) said: There is no good for you in this. He (Qaz'a), however, repeated (his demand). He then said: The noon prayer would start and one of us would go to Baqi' and, having relieved himself, would come to his home, then perform ablution and go to the mosque, and (he would find) The Messenger of Allah (ﷺ) in the first rak'ah.
