Abu Dawud

Abu Saeed said: we were commanded to recite Fatihat al-kitab and whatever was convenient (from the Quran during the prayer).

Abu Hurairah reported the Messenger of Allah ﷺ as saying: Go out and announce in Madina that prayer is not valid but the recitation of the Quran even though it might be fatihat al-kitab and something more.

Abu Hurairah said: The Messenger of Allah ﷺ commanded me to announce that prayer is not valid but with the recitation of Fatihat al-kitab and something more.

Abu Hurairah reported the Messenger of Allah ﷺ as saying: If anyone observes a prayer in which he does not recite Umm al-Quran, it is incomplete, it is incomplete, it is incomplete, and deficient. (The narrator said) I said: Abu Hurairah, sometime I pray behind the imam (then what should I do)? Pressing my hand he replied: O Persian, recite it inwardly, for I heard the Messenger of Allah ﷺ as saying that Allah, Most High, has said: I have Me and the Half for my servant and My servant will receive what he asks. The Messenger of Allah ﷺ said: Recite. When the servant says: “praise be to Allah, the Lord of the Universe, ” Allah, Most High says: “My servant has praised me. ” When the servant says: “ The Compassionate, the merciful, “Allah Most High says: “My servant has lauded me. ” When the servant says: “Owner of the Day of Judgment, ” Allah, Most High, says: “My servant has glorified Me” When the servant says: “ Thee do we worship and of thee we ask help. “ (Allah says) “This is between Me and My servant, and My servant will receive what he asks. ” When the servant says: “ Guide us to the Straight Path, the path of those whom thou hast favoured, not ( the path) of those who earn thine anger nor of those who go astray, ” (Allah says: ) “This is for My servant, and My servant will receive what he asks. ”

Ubadah bin al-Samit reported the Messenger of Allah ﷺ as saying: the prayer is not valid I one does not recite fatihat al-kitab and something more, sufyan ( the narrator) said: This applies to a man who prays alone.

Narrated Ubadah ibn as-Samit: We were behind the Messenger of Allah ﷺ at the dawn prayer, and he recited (the passage), but the recitation became difficult for him. Then when he finished, he said: Perhaps you recite behind your imam? We replied: Yes, it is so, Messenger of Allah. He said: Do not do so except when it is Fatihat al-Kitab, for he who does not recite it is not credited with having prayed.

Nafib. Mahmudb. Al-Rabi Al-Ansari said: “Ubadah bin al-Samit came to late to lead the morning prayer. Abu Nuaim, the Muadhdhin, pronounced the takbir and he led the people in prayer. Then Ubadah came and I was with him. We Joined the row behind Abu Nuaim, while Abu Nuaim was reciting the Quran loudly. Then Ubadah began to recite the Umm al-Quran (I. e Surah al Fatihah). When he finished, I said to Ubadah: I heard you reciting the Umm al-Quran while Abu Nuaim was reciting Quran loudly. He replied: yes> The Messenger of Allah ﷺ led us in a certain prayer in which the Quran is recited loudly, but he became confused in the recitation. When he finished he turned his face to us and said: Do you recite when I recite the Quran loudly? Some of us said: we do so; this is why I said to myself: What is that which confused me (in the recitation of ) the Quran. Do not recite anything from the Quran when I recite it loudly except the Umm al-Quran.

The above mentioned tradition has been transmitted through a different chain of narrators by Ubadah bin al-Samit like the version of al-Rabib Sulaiman. This version adds: Makhul used to recite Surah al Fatihah al-kitab quietly in the prayer in which the imam recites the Quran loudly when he observes the period of silence. If he does not observe the period of silence, recite it before him (i. e before his recitation), or along with him or after him; do not give it up in any case.
