"We were with the Messenger of Allah (ﷺ) when a man entered the Masjid and prayed. The Messenger of Allah (ﷺ) watched him without him realizing, then he finished, came to the Messenger of Allah (ﷺ) and greeted him with salam. He returned the salam and said: "Go back and pray, for you have not prayed.'" He (the narrator) said: "I do not know if it was the second or third time,- "(the man) said: 'By the One Who revealed the Book to you, I have tried my best. Teach me and show me.' He said: 'When you want to pray, perform wudu' and do it well, then stand up and face the qiblah. Then say the takbir, then recite, then bow until you are at ease in bowing. Then stand up until you are standing up straight. Then prostrate until you are at ease in prostration, then raise your head until you are at ease in sitting, then prostrate until you are at ease in prostration. If you do that then you will have done your prayer properly, and whatever you failed to do properly is going to detract from your prayer."

"I heard Anas narrate that the Prophet (ﷺ) said: "Bow and prostrate properly when you bow and prostrate.'"

"My father told me: 'I prayed behind the Messenger of Allah (ﷺ) and I saw him raise his hands when he started to pray, and when he bowed, and when he said: Sami' Allahu liman hamidah (Allah hears the one who praises Him)" like this.'" And (one of the narrators) Qais pointed towards his ears.

When the Messenger of Allah (ﷺ) started to pray, he raised his hands until they were in level with his shoulders, and when he said the takbir before bowing, and when he raised his head from bowing he raised (his hands) likewise, and said: "Sami Allahu liman hamidah Rabbana wa lakal-hamd (Allah hears the one who praises Him; Our Lord, and to You be praise)," and he did not do that when prostrating.

The Prophet (ﷺ) fell from a horse onto his right side, and they entered upon him to visit him. The time for prayer came, and when he had finished praying he said: "The Imam is appointed to be followed, so when he bows, then bow, and when he stands up, then stand up, and when he says: 'Sami' Allahu liman hamidah (Allah hears the one who praises Him)' then say: 'Rabbana wa lakal-hamd (Our Lord, and to You be the praise).'"

"We were praying behind the Messenger of Allah (ﷺ) one day and when he raised his head from bowing he said: 'Sami Allahu liman hamidah (Allah hears the one who praises Him).' A man behind him said: 'Rabbana wa lakal-hamd, hamdan kathiran tayyiban mubarakan fih. (O our Lord, and to You be praise, much blessed and pure praise.)' When the Messenger of Allah (ﷺ) had finished, he said: "Who is the one who spoke just now?" The man said: 'I did, O Messenger of Allah.' The Messenger of Allah (ﷺ) said: 'I saw thirty-some angels rushing to see which of them would write it down first.'"

"When the Messenger of Allah (ﷺ) raised his head in the second rak'ah of the subh prayer, he said: 'O Allah, save Al-Walid bin Al-Walid and Salamah bin Hisham and 'Ayyshah bin Abi Rabi'ah and those who are weak and oppressed in Makkah. O Allah, intensify Your punishment in Mudar and give them years (of famine) like the years of Yusuf.'"

The Messenger of Allah (ﷺ) used to supplicate in prayer when he said: "Sami' Allahu liman hamidah, Rabbana wa lakal-hamd (Allah hears those who praise Him; O our Lord, and to You be praise),"then he said while standing, before he prostrated: "O Allah, save Al-Walid bin Al-Walid and Salamah bin Hisham and 'Ayyshah bin Abi Rabi'ah and those who are weak and oppressed in Makkah. O Allah, intensify Your punishment in Mudar and give them years (of famine) like the years of Yusuf." Then he would say: "Allah is Most Great" and then he prostrated. The people of Mudar and their environs were opposed to the Messenger of Allah (ﷺ) at the time.

"Imran bin Husain and I prayed behind Ali bin Abi Talib. When he prostrated he said the Takbir, and when he raised his head from prostration he said the takbir, and when he stood up following two rak'ahs he said the takbir, and when he had finished praying, 'Imran took my hand and said: 'This reminded me of- he said a word meaning- the prayer of Muhammad (ﷺ).'"

"The Messenger of Allah (ﷺ) used to say the takbir every time he went down and came up, and he would say the Salam to his right and his left. And Abu Bakr and 'Umar used to do likewise."

"The Messenger of Allah (ﷺ) said: 'When one of you prostrates, let him put his hands down before his knees, and not kneel like a camel.'"

The hands prostrate as the face prostrates, so when one of you puts his face down he should put his hands down, and when he raises (the face) he should raise (the hands) too.

"The Prophet (ﷺ) forbade me from wearing A-Qassi and silk, and gold rings, and from reciting Qur'an when bowing."

"The Prophet (ﷺ) drew back the curtain when the people were in rows behind Abu Bakr, may Allah be pleased with him, and said: 'O people, there is nothing left of the features of Prophethood except a good dream that a Muslim sees or is seen by others for him.' Then he said: 'Verily, I have been forbidden from reciting the Qur'an when bowing or prostrating. As for bowing, glorify the Lord therein, and as for prostration, strive hard in supplication for it is more deserving of a response.'"

When the Messenger of Allah (ﷺ) bowed, he said: "Allahumma laka rak`atu was laka aslamtu wa bika amantu, khasha`a laka sam`i wa basri wa `izami wa mukhi wa `asabi (O Allah, to You I have bowed and to You I have submitted and in You I have believed. My hearing, sight, bones, brain and sinews are humbled before You)."

When the Messenger of Allah (ﷺ) stood to offer a voluntary prayer, he would say when he bowed: "Allahumma laka rak'atu wa bika amantu wa laka aslamtu wa alayka tawwakaltu, anta Rabbi, khasha'a sam'i wa basri wa lahmi wa dammi wa mukhi wa 'asabi Lillahi Rabbil-'Alamin ( O Allah, to You I have bowed, in You I believe, to You I have submitted and in You I put my trust. You are my Lord. My hearing, my sight, my flesh, my blood, my brain and my sinews are humbled before Allah, the Lord of the Worlds)."

He saw the Prophet (ﷺ) raise his hands when he bowed, and when he raised his head from bowing, until they were in level with the highest part of his ears.

The bowing of the Messenger of Allah (ﷺ), and when he raised his head from bowing, and his prostration, and the time between the two prostration, were almost equal in length.

When the Prophet (ﷺ) wanted to prostrate after bowing, he would say: "Allahumma, Rabbana wa lakal-hamd, mil'as-samawati wa mil'al-ardi wa mil'ama shi'ta min shai'in ba'd ( O Allah, our Lord, to You be the Praise, filling the heavens, filling the Earth, and filling whatever else You will.)"

The Messenger of Allah (ﷺ) used to say: "Sami Allahu liman hamidah, Rabbana wa lakal-hamd, mil'as-samawati wa mil'al-ardi wa mil'ama shi'ta min shai'in ba'd. Athlath-thana'i wal-majdi khairu ma qalal-'abdu wa kulluna laka 'abdun la mani'a lima a'taita wa la yanfa'u dhal-jaddi minkal-jadd (Allah hears the one who praises Him; Our Lord, to You be the Praise, filling the heavens, filling the Earth, and filling whatever else You will, Lord of Glory and Majesty, the truest thing a slave had said, and we are all slaves to You. None can withhold what You grant, nor can the possession of an owner benefit him before You.)"
