‘Ā’ishah (may Allah be pleased with her) reported: I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say: "No prayer should be offered in the presence of food or when he is resisting the need to relieve himself of the two filths."

‘Uthmān ibn Abi al-‘Ās (may Allah be pleased with him) reported: I came to the Prophet (may Allah's peace and blessings be upon him) and said: "O Messenger of Allah, Satan intervenes between me and my prayer and my recitation of the Qur'an, confounding me." So, the Messenger of Allah (may Allah's peace and blessings be upon him) said: "That is Satan who is known as Khinzab. If you perceive his effect, seek refuge with Allah from him and spit three times to your left." He said: I did that, and Allah caused him to depart from me.

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah’s peace and blessings be upon him) said: "The worst of thieves among people is the one who steals his prayer." He said: "How does he steal his prayer?" He said: "He does not perform its Rukū‘ or prostration perfectly."

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Is he who raises his head before the Imam not afraid that Allah may transform his head into that of a donkey or his shape into that of a donkey?"

Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "When anyone of you is in doubt about his prayer, not knowing how much he prayed, three or four, let him dispel the doubt and build upon what he is certain about, then perform two prostrations before making Taslīm. If he has prayed five, they will make his prayer even-numbered, and if he has prayed exactly four, they will be humiliation for the devil."

Wābisah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) saw a man praying alone behind the row, so he commanded him to repeat his prayer.

‘Abdullah ibn Mas‘ūd (may Allah be pleased with him) reported: It was mentioned before the Prophet (may Allah's peace and blessings be upon him) about a man who slept throughout the night until morning. He said, "That is a man in whose ears—or, he said, in whose ear—the devil urinated."

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "The best day upon which the sun has risen is Friday; on it Adam was created, on it he was admitted to Paradise, on it he was expelled therefrom, and the Hour will not take place except on Friday."

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Whoever takes a bath on Friday, like the bath taken from sexual impurity, and then goes (to the mosque) is like the one who offers a camel as a sacrifice; whoever goes at the second hour is like the one who offers a cow as a sacrifice; whoever goes at the third hour is like the one who offers a horned ram as a sacrifice; whoever goes at the fourth hour is like the one who offers a chicken as a sacrifice; and whoever goes at the fifth hour is like one who offers an egg as a sacrifice. When the Imām comes out, the angels come to listen to the Dhikr."

Thawbān (may Allah be pleased with him) reported: When the Messenger of Allah (may Allah's peace and blessings be upon him) finished his prayer, he would seek Allah’s forgiveness three times and say: "Allahumma anta as-salām wa minka as-salām, tabārakta yadha al-jalāl wa al-ikrām (O Allah, You are As-Salām (peace, perfection), and as-salām comes from You. Blessed are You, O Possessor of Glory and Honor)". Al-Walīd said: I said to Al-Awzā‘i: "How is the seeking of forgiveness?" He said: "You say: Astaghfirullāh, astaghfirullāh (I seek forgiveness from Allah, I seek forgiveness from Allah)."

Abu az-Zubayr reported: Ibn az-Zubayr (may Allah be pleased with him) used to say after every prayer after making taslīm: “Lā ilāha illa Allah wahdahu lā sharīka lahu, lahu al-mulk wa lahu al-hamd wa huwa ‘ala kolli shay‘in qadīr; lā hawla wa lā quwwata illa billāh, lā ilāha illa Allah, wa lā na‘budu illa iyyāh, lahu an-ni‘mah wa al-fadl, wa lahu ath-thanā’ al-hasan; lā ilāha illa Allah, mukhlisīn lahu ad-dīn wa law kariha al-kāfirūn (There is no god but Allah, alone, with no partner. To Him belongs the dominion, and praise is due to Him, and He has power over all things. There is no power or strength except through Allah. There is no god but Allah, and we worship none but Him. To Him belongs the blessing, to Him belongs the grace, and to Him belongs all excellent praise. There is no god but Allah; we are sincerely devoted to Him, even if the disbelievers may dislike it)." And he said: "The Messenger of Allah (may Allah's peace and blessings be upon him) used to celebrate Allah’s oneness with these words after every prayer."

Warrād, the scribe of Al-Mughīrah ibn Shu‘bah, related: Al-Mughīrah ibn Shu‘bah dictated to me in a letter to Mu‘āwiyah: The Prophet (may Allah’s peace and blessings be upon him) used to say after every obligatory prayer: "Lā ilāh illa Allah, wahdahu lā sharīka lah, lahu al-mulku wa lahu al-hamdu wa huwa ‘ala koll shay’in qadīr, allahumma lā māni‘a lima a‘tayt wa lā mu‘tiya lima mana‘ta wa la banfa‘u dha al-jaddi minka al-jadd" (There is no god but Allah, alone, with no partner with Him. To Him belongs the dominion and to Him praise is due, and He is Able to do all things. O Allah, none can withhold what You give and none can give what You withhold, and riches cannot avail a wealthy person against You).
