Originally, two rak`at were prescribed in every prayer. When the Prophet migrated (to Medina) four rak`at were enjoined, while the journey prayer remained unchanged(i.e. two rak`at).

Once a man said to Allah's Apostle "O Allah's Apostle! I may not attend the (compulsory congregational) prayer because so and so (the Imam) prolongs the prayer when he leads us for it. The narrator added: "I never saw the Prophet more furious in giving advice than he was on that day. The Prophet said, "O people! Some of you make others dislike good deeds (the prayers). So whoever leads the people in prayer should shorten it because among them there are the sick the weak and the needy (having some jobs to do).

One of the wives of `Umar (bin Al-Khattab) used to offer the Fajr and the `Isha' prayer in congregation in the Mosque. She was asked why she had come out for the prayer as she knew that `Umar disliked it, and he has great ghaira (self-respect). She replied, "What prevents him from stopping me from this act?" The other replied, "The statement of Allah's Apostle : 'Do not stop Allah's women-slaves from going to Allah's Mosques' prevents him."

The Prophet said, "Night prayer is offered as two rak`at followed by two rak`at and so on, and if you want to finish it, pray only one rak`a which will be witr for all the previous rak`at." Al-Qasim said, "Since we attained the age of puberty we have seen some people offering a three-rak`at prayer as witr and all that is permissible. I hope there will be no harm in it."

Sa'd ibn Hisham said: I came to Medina and called upon Aisha, and said to her: Tell me about the prayer of the Messenger of Allah (saws).

She said: The Messenger of Allah (saws) used to lead the people in the night prayer, and then go to his bed and sleep. When midnight came he got up, went to answer the call of nature and to perform ablution with water. Having performed ablution, he entered the mosque and prayed eight rak'ahs.

To my mind he performed the recitation of the Qur'an, bowing and prostrating equally. He then observed witr with one rak'ah and prayed two rak'ahs sitting. Then he lay down on the ground. Sometimes Bilal came to him and called him for prayer. He then dozed, and sometimes I doubted whether he dozed or not, till he (Bilal) called him for prayer.

This is the prayer he offered till he grew old or put on weight. She then mentioned how he put on weight as Allah wished.

`Ata' told me that he had heard Jabir bin `Abdullah saying, "The Prophet stood up to offer the prayer of the `Id ul Fitr. He first offered the prayer and then delivered the Khutba. After finishing it he got down (from the pulpit) and went towards the women and advised them while he was leaning on Bilal's hand. Bilal was spreading out his garment where the women were putting their alms." I asked `Ata' whether it was the Zakat of `Id ul Fitr. He said, "No, it was just alms given at that time. Some lady put her finger ring and the others would do the same." I said, (to `Ata'), "Do you think that it is incumbent upon the Imam to give advice to the women (on `Id day)?" He said, "No doubt, it is incumbent upon the Imams to do so and why should they not do so?"

Once the Iqama was pronounced and the Prophet was talking to a man (in a low voice) in a corner of the mosque and he did not lead the prayer till (some of) the people had slept (dozed in a sitting posture) .

The Prophet said, "Whoever slaughtered the sacrifice before the prayer, he just slaughtered it for himself, and whoever slaughtered it after the prayer, he slaughtered it at the right time and followed the tradition of the Muslims."

My father said, "The Prophet used to prolong the first rak`a of the Zuhr prayer and shorten the second one and used to do the same in the Fajr prayer."

Once we were traveling with the Prophet and we carried on traveling till the last part of the night and then we (halted at a place) and slept (deeply). There is nothing sweeter than sleep for a traveler in the last part of the night. So it was only the heat of the sun that made us to wake up and the first to wake up was so and so, then so and so and then so and so (the narrator `Auf said that Abu Raja' had told him their names but he had forgotten them) and the fourth person to wake up was `Umar bin Al- Khattab. And whenever the Prophet used to sleep, nobody would wake up him till he himself used to get up as we did not know what was happening (being revealed) to him in his sleep. So, `Umar got up and saw the condition of the people, and he was a strict man, so he said, "Allahu Akbar" and raised his voice with Takbir, and kept on saying loudly till the Prophet got up because of it. When he got up, the people informed him about what had happened to them. He said, "There is no harm (or it will not be harmful). Depart!" So they departed from that place, and after covering some distance the Prophet stopped and asked for some water to perform the ablution. So he performed the ablution and the call for the prayer was pronounced and he led the people in prayer. After he finished from the prayer, he saw a man sitting aloof who had not prayed with the people. He asked, "O so and so! What has prevented you from praying with us?" He replied, "I am Junub and there is no water. " The Prophet said, "Perform Tayammum with (clean) earth and that is sufficient for you." Then the Prophet proceeded on and the people complained to him of thirst. Thereupon he got down and called a person (the narrator `Auf added that Abu Raja' had named him but he had forgotten) and `Ali, and ordered them to go and bring water. So they went in search of water and met a woman who was sitting on her camel between two bags of water. They asked, "Where can we find water?" She replied, "I was there (at the place of water) this hour yesterday and my people are behind me." They requested her to accompany them. She asked, "Where?" They said, "To Allah's Apostle ." She said, "Do you mean the man who is called the Sabi, (with a new religion)?" They replied, "Yes, the same person. So come along." They brought her to the Prophet and narrated the whole story. He said, "Help her to dismount." The Prophet asked for a pot, then he opened the mouths of the bags and ...

We used to greet the Prophet while he was praying and he used to answer our greetings. When we returned from An-Najashi (the ruler of Ethiopia), we greeted him, but he did not answer us (during the prayer) and (after finishing the prayer) he said, "In the prayer one is occupied (with a more serious matter)."
