Buraydah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah’s peace and blessings be upon him) said: "The covenant between us and them is prayer; so, whoever abandons it has disbelieved."

Jābir (may Allah be pleased with him) reported: I heard the Prophet (may Allah’s peace and blessings be upon him) say: "What stands between a man and polytheism and disbelief is the abandonment of the prayers."

Sālim ibn Abu al-Ja‘d reported: A man said: "I wish I had prayed and got comfort." When the people seemed to disapprove of his statement, he said: "I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say: 'O Bilāl, call the Iqāmah for the prayer; give us comfort by it.'"

Abu Hurayrah (may Allah be pleased with him) reported: When the Messenger of Allah (may Allah's peace and blessings be upon him) made Takbīr in the prayer, he would remain silent a while before reciting. I said: O Messenger of Allah, may my father and mother ransom you! Have you seen your silence between Takbīr and the recitation? What is it that you say? He said: "I say: Allāhumma bā‘id bayni wa bayna khatāyāy kama bā‘dta bayna al-mashriqi wa al-maghrib. Allāhumma naqqini min khatāyāy kama yunaqqa ath-thawbu al-abyadu min ad-danas. Allāhumma ighsilni min khatāyāy bith-thalji wa al-mā’i wa al-barad (O Allah, distance me from my sins as You have distanced the east from the west. O Allah, purify me from my sins as a white garment is purified from dirt. O Allah, wash out my sins with water, snow, and hail)."

Ibn ‘Umar (may Allah be pleased with him and his father) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) used to raise his hands in line with his shoulders when commencing the prayer, when saying Takbīr (proclaiming Allah's greatness) for Rukū‘ (bowing), and when raising his head from Rukū‘ he would raise them as well and say: "Sami‘allāhu liman hamidah, rabbana wa laka al-hamd" (Allah hears whoever praises Him, O our Lord, praise be to You). He did not use to do this in Sujūd (prostration).

‘Ubādah ibn as-Sāmit (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "The prayer of the one who did not recite the Opening of the Book (Surat al-Fātihah) is invalid."

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) entered the mosque, and then a man came in and prayed. He greeted the Prophet (may Allah's peace and blessings be upon him), who responded and said: "Go back and pray, for you have not prayed." He went back and prayed as he had prayed, then, he came to the Prophet (may Allah's peace and blessings be upon him) and greeted him. He said: "Go back and pray, for you have not prayed," three times. So, he said: By the One Who sent you with the truth, I cannot do better than that. So teach me. He said: "When you stand to pray, say Takbīr (Allāhu Akbar), then recite whatever you can of the Qur’an; then bow until you are at ease in bowing; then rise until you are standing up straight; then prostrate until you are at ease in prostration; and then sit up until you are at ease in sitting. Do that throughout your prayer."

Abu Hurayrah (may Allah be pleased with him) reported that he used to say takbīr in every obligatory and supererogatory prayer during Ramadan and others. He would say takbīr when he rose and say takbīr when he bowed. Then, he would say: "Sami'a allāhu liman hamidah" (Allah hears he who praises Him). Then, he would say, "Rabbanā wa laka al-hamd" (Our Lord, praise be to You) before prostrating. Then, he would say: "Allāhu akbar" (Allah is the Greatest) as he went down to prostration. Then, he would say takbīr upon raising his head from prostration, then say takbīr upon prostrating, and then say takbīr upon raising his head from prostration. Then, he would say takbīr upon rising from the sitting position both times. He would do so in every Rak'ah until he finished the prayer. Then, he would say as he left: "By the One in Whose Hand my soul is, I am the closest among you to the prayer of the Messenger of Allah (may Allah's peace and blessings be upon him). Such was his prayer until he departed this world."

Ibn ‘Abbās (may Allah be pleased with him and his father) reported that the Prophet (may Allah's peace and blessings be upon him) said: "I have been commanded to prostrate on seven bones: the forehead (and he pointed to his nose), the hands, the knees, and the extremities of the feet, and not to tuck up the clothes and hair."

Abu ’Umāmah reported: ‘Amr ibn ‘Abasah (may Allah be pleased with him) related to me that he heard the Prophet (may Allah's peace and blessings be upon him) say: "The nearest the Lord to a servant is in the course of the last part of the night. So, if you are able to be among those who remember Allah at that hour, do so."

Jarīr ibn ‘Abdullah (may Allah be pleased with him) reported: We were in the presence of the Prophet (may Allah's peace and blessings be upon him) when he looked at the moon when it was full, and he said: "You will see your Lord as you see this moon, you will not have any difficulty in seeing Him. So if you are able to not be overcome in observing a prayer before sunrise (the Fajr) and a prayer before sunset (the ‘Asr), then do so." Then, he recited: "{And glorify the praise of your Lord before sunrise and before sunset.}"

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) recited: {Say, “O disbelievers”} and {Say: “He is Allah, the One”} in the two Rak‘ahs of Fajr.
