When the Prophet, became ill in his fatal illness, Someone came to inform him about the prayer, and the Prophet (ﷺ) told him to tell Abu Bakr to lead the people in the prayer. I said, "Abu Bakr is a softhearted man and if he stands for the prayer in your place, he would weep and would not be able to recite the Qur'an." The Prophet (ﷺ) said, "Tell Abu Bakr to lead the prayer." I said the same as before. He (repeated the same order and) on the third or the fourth time he said, "You are the companions of Joseph. Tell Abu Bakr to lead the prayer." So Abu Bakr led the prayer and meanwhile the Prophet (ﷺ) felt better and came out with the help of two men; as if I see him just now dragging his feet on the ground. When Abu Bakr saw him, he tried to retreat but the Prophet (ﷺ) beckoned him to carry on. Abu Bakr retreated a bit and the Prophet (ﷺ) sat on his (left) side. Abu Bakr was repeating the Takbir (Allahu Akbar) of Allah's Messenger (ﷺ) for the people to hear.

The Prophet (ﷺ) prayed two rak`at of Zuhr prayer (instead of four) and he was told that he had prayed two rak`at only. Then he prayed two more rak`at and finished them with the Taslim followed by two prostrations.

Once the Iqama was pronounced and Allah's Messenger (ﷺ) faced us and said, "Straighten your rows and stand closer together, for I see you from behind my back.'

The Prophet (ﷺ) said, "Martyrs are those who die because of drowning, plague, an Abdominal disease, or of being buried alive by a falling building." And then he added, "If the people knew the Reward for the Zuhr prayer in its early time, they would race for it. If they knew the reward for the `Isha' and the Fajr prayers in congregation, they would join them even if they had to crawl. If they knew the reward for the first row, they would draw lots for it."

The Prophet (ﷺ) said, "Straighten your rows for I see you from behind my back." Anas added, "Everyone of us used to put his shoulder with the shoulder of his companion and his foot with the foot of his companion."

Allah's Messenger (ﷺ) made a small room in the month of Ramadan (Sa`id said, "I think that Zaid bin Thabit said that it was made of a mat") and he prayed there for a few nights, and so some of his companions prayed behind him. When he came to know about it, he kept on sitting. In the morning, he went out to them and said, "I have seen and understood what you did. You should pray in your houses, for the best prayer of a person is that which he prays in his house except the compulsory prayers."

Allah's Messenger (ﷺ) fell from a horse and got injured so he led the prayer sitting and we also prayed sitting. When he completed the prayer he said, "The Imam is to be followed; if he says Takbir then say Takbir, bow if he bows; raise your heads when he raises his head, when he says, 'Sami`a l-lahu liman hamidah say, 'Rabbana laka l-hamd', and prostrate when he prostrates."

Whenever Ibn `Umar started the prayer with Takbir, he used to raise his hands: whenever he bowed, he used to raise his hands (before bowing) and also used to raise his hands on saying, "Sami`a l-lahu liman hamidah", and he used to do the same on rising from the second rak`a (for the 3rd rak`a). Ibn `Umar said: "The Prophet (ﷺ) used to do the same."

The Prophet (ﷺ) said, "Perform the bowing and the prostrations properly. By Allah, I see you from behind me (or from behind my back) when you bow or prostrate."

Allah's Messenger (ﷺ) used to keep silent between the Takbir and the recitation of Qur'an and that interval of silence used to be a short one. I said to the Prophet (ﷺ) "May my parents be sacrificed for you! What do you say in the pause between Takbir and recitation?" The Prophet (ﷺ) said, "I say, 'Allahumma, baa`id baini wa baina khatayaya kama baa`adta baina l-mashriqi wa l-maghrib. Allahumma, naqqini min khatayaya kama yunaqqa th-thawbu l-abyadu mina d-danas. Allahumma, ighsil khatayaya bi l-maa'i wa th-thalji wa l-barad (O Allah! Set me apart from my sins (faults) as the East and West are set apart from each other and clean me from sins as a white garment is cleaned of dirt (after thorough washing). O Allah! Wash off my sins with water, snow and hail.)"

Once solar eclipse occurred during the lifetime of Allah's Messenger (ﷺ). He offered the eclipse prayer. His companions asked, "O Allah's Messenger (ﷺ)! We saw you trying to take something while standing at your place and then we saw you retreating." The Prophet (ﷺ) said, "I was shown Paradise and wanted to have a bunch of fruit from it. Had I taken it, you would have eaten from it as long as the world remains."

The Prophet (ﷺ) saw expectoration in the direction of the Qibla of the mosque while he was leading the prayer, and scratched it off. After finishing the prayer, he said, "Whenever any of you is in prayer he should know that Allah is in front of him. So none should spit in front of him in the prayer."

Allah's Messenger (ﷺ) said, "Whoever does not recite Al-Fatiha in his prayer, his prayer is invalid."

My father said, "The Prophet (ﷺ) in Zuhr prayers used to recite Al-Fatiha along with two other Suras in the first two rak`at: a long one in the first rak`a and a shorter (Sura) in the second, and at times the verses were audible. In the `Asr prayer the Prophet (ﷺ) used to recite Al-Fatiha and two more Suras in the first two rak`at and used to prolong the first rak`a. And he used to prolong the first rak`a of the Fajr prayer and shorten the second.

My father said, "The Prophet (ﷺ) used to recite Al-Fatiha along with another Sura in the first two rak`at of the Zuhr and the `Asr prayers and at times a verse or so was audible to us."

My father said, "I heard Allah's Messenger (ﷺ) reciting "at-Tur" (52) in the Maghrib prayer."

Once I prayed the `Isha' prayer with Abu Huraira and he recited, "Idha s-samaa'u n-shaqqat" (84) and prostrated. I said, "What is that?" He said, "I prostrated behind Abul-Qasim, (the Prophet) (when he recited that Sura) and I will go on doing it till I meet him."

My father and I went to Abu Barza-al-Aslami to ask him about the stated times for the prayers. He replied, "The Prophet (ﷺ) used to offer the Zuhr prayer when the sun just declined from its highest position at noon; the `Asr at a time when if a man went to the farthest place in Medina (after praying) he would find the sun still hot (bright). (The sub narrator said: I have forgotten what Abu Barza said about the Maghrib prayer). The Prophet (ﷺ) never found any harm in delaying the `Isha' prayer to the first third of the night and he never liked to sleep before it and to talk after it. He used to offer the morning prayer at a time when after finishing it one could recognize the person sitting beside him and used to recite between 60 to 100 verses in one or both the rak`at."

A man came to Ibn Mas`ud and said, "I recited the Mufassal (Suras) at night in one rak`a." Ibn Mas`ud said, "This recitation is (too quick) like the recitation of poetry. I know the identical Suras which the Prophet (ﷺ) used to recite in pairs." Ibn Mas`ud then mentioned 20 Mufassal Suras including two Suras from the family of (i.e. those verses which begin with) Ha, Meem [??] (which the Prophet (ﷺ) used to recite) in each rak`a.

The Prophet (ﷺ) said, "Say Amin" when the Imam says it and if the Amin of any one of you coincides with that of the angels then all his past sins will be forgiven." Ibn Shihab said, "Allah's Messenger (ﷺ) used to Say "Amin."
