Sulayman, the freed slave of Maymunah, said: I came to Ibn Umar at Bilat (a place in Medina) while the people were praying. I said: Do you not pray along with them? He said: I heard the Messenger of Allah (ﷺ) say: Do not say a prayer twice in a day.

The one of you who is most versed in the Books of Allah should act as imam for the people; and the one who is the earliest of them in reciting (the Qur’an); if they are equally versed in reciting it, then the earliest of them to emigrate (to Medina); if they emigrated at the same time, then the oldest of them. No man must lead another in prayer in his house (i.e. in the house of a latter) or where the latter has authority, or sit in his place of honor without his permission. Shu’bah said: I asked Isma’il: what is the meaning of his place of honor? He replied: his throne.

The Prophet (ﷺ) said: There are three types of people whose prayer is not accepted by Allah: One who goes in front of people when they do not like him; a man who comes dibaran, which means that he comes to it too late; and a man who takes into slavery an emancipated male or female slave.

The obligatory prayer is essential behind every Muslim, pious or impious, even if he has committed a sins.

‘Ammar came forward and stood on a shop (or a beach) and prayed while the people stood on a lower place than he. Hudaifah came forward and took him by the hands and Ammar followed him till Hudaifah brought him down. When ‘Ammar finished his prayer. Hudaifah said to him: Did you not hear the Messenger of Allah (May peace be upon him) say: When a man leads the people in prayer, he must not stand in a position higher than theirs, or words to that effect? ‘Ammar replied : that is why I followed you when you took me by the hand.

The Prophet (ﷺ) said: The imam is appointed only to be followed. This version adds: When he recites (the Qur'an), keep silent."

Abu Dawud said: The addition of the words "When he recites, keep silent" in this version are not guarded. The misunderstanding, according to us, is on the part of Abu Khalid (a narrator).

when I was spending a night in the house of my maternal aunt Maimunah, the Messenger of Allah (ﷺ) got up at night, opened the mouth of the water skin and performed ablution. He then closed the mouth of the water-skin and stood for prayer. Then I got up and performed ablution as he did ; then I came and stood on his left side.

I had a sheet of cloth upon me, and I began to cross both the ends, but they did not reach (my shoulders). It had fringes which I turned over and crossed the two ends, and bowed down retaining it with my neck lest it should fall down. Then I came and stood on the left side of the Messenger of Allah (ﷺ). He then took and brought me around him and set me on his right side. Then Ibn Sakhr came and stood on his left side. he then took us with his both hands and made us stand behind him. The Messenger of Allah (ﷺ) began to look at me furtive glances, but I could not understand. When I understood, he hinted at me tie the wrapper. When the Messenger of Allah (ﷺ) finished the prayer, he said (to me): O Jabir. I said; Yes, Messenger of Allah. He said; if it (the sheet) is wide, cross both its ends (over the shoulders); if it is tight, tie it over your loins.

The Messenger of Allah (ﷺ) prohibited us to pray in a sheet of cloth without crossing both its ends, and he also prohibited us to pray in a wrapper without putting on a sheet.
