Hazm bin Ubayy bin Kaab said that he came to Muadh bin Jabal who was leading the people in the sunset prayer. According to this version, the Messenger of Allah ﷺ said: O Muadh, do not become a trouble, because the aged, the weak, the needy and the traveler pray behind you.

Narrated Some Companions of the Prophet: Abu Salih reported on the authority of some Companions of the Prophet ﷺ: The Prophet ﷺ said to a person: what do you say in prayer? He replied: I first recite tashahhud (supplication recited in sitting position), and then I say: O Allah, I ask Thee for Paradise, and I seek refuge in Thee from Hell-Fire, but I do not understand your sound and the sound of Muadh (what you say or he says in prayer). The Prophet ﷺ said: We too go around it (paradise and Hell-fire).

Jabir narrated the story of Muadh and said: The prophet ﷺ said to a youth: My nephew, what do you do in prayer? He replied: I recited fatihat al-katab and I ask Allah for paradise and seek his refuge from hell-fire I do not understand well your sound and the sound of Muadh. The prophet ﷺ said: I and Muadh go around both (paradise and Hell-fire), or he said something similar.

Abu Hurairah reported the prophet ﷺ as saying: When one of you leads the people in prayer, he should be brief, for among them are the weak, the sick, and the aged. But when one of you prays by himself, he may pray as long as he likes.

Abu Hurairah reported the prophet ﷺ as saying: when one of you leads the people in prayer, he should be brief, for among them are the sick, the aged and the needy.

Ammar bin Yasir said: I heard the Messenger of Allah ﷺ say: A man returns after saying his prayer while a tenth part of his prayer, or a ninth part, or an eight part, or a seventh part, or a sixth part, or a fifth part, or a third part, or half of it, is recorded for him.

Abu Hurairah said: In every prayer there is a recitation. We make you listen what the Messenger of Allah ﷺ made us listen, and we keep hidden from you what he kept hidden from us.

Abu Qatadah said: The Messenger of Allah ﷺ used to lead us in prayer and recite in the first two rak’ahs of the noon prayers Fatihat al-kitab and two surahs, and he would sometimes recite loud enough for us to hear the verse. He would prolong the first rak’ah of the noon prayer and shorten the second; and he did so in the morning prayer. Abu Dawud said: Musaddad did not mention the words fatihat al-kitab and surah.

The above mentioned tradition as been reported by Abu Qatadah through a different chain of narrators. This version adds: He would recite Fatihat al-kitab in the last two surahs. Hammam added: He would prolong the first rak’ah but would not prolong the second so much; and he did so similarly in the afternoon prayer, and so in the morning prayer.

Abu Qatadah said: We thought that by this (prolonging the first rak’ah). He (the prophet) meant that the people might join the first rak’ah.
