Ibn ‘Umar said that when the Muslims came to Medina they gathered and sought to know the time of prayer, but no one summoned them. One day they discussed the matter, and one of them said, “Use something like the bell of the Christians." Another said, “Use a horn like that of the Jews." But when ‘Umar said, “I suggest that you send a man to announce the prayer," God’s Messenger said, “Get up, Bilal, and summon to prayer." (Bukhari and Muslim.)

Abu Huraira reported God’s Messenger as saying, “When a summons to prayer is made the evil turns his back and breaks wind so as not to hear the call being made, but when the summons is finished he turns round. When a second call to prayer is made he turns his back, and when the second call is finished he turns round to distract a man, saying, ‘Remember such and such ; remember such and such’, referring to something the man did not have in mind, with the result that he does not know how much he has prayed.” (Bukhari and Muslim.)

Jabir reported God’s Messenger as saying: If anyone says when he hears the summons, “O God, Lord of this perfect call and of the prayer which is established for all time, grant Muhammad the wasila and excellency, and raise him up in a praiseworthy position (Al-Qur’an; 17:79) which Thou hast promised,” he will be assured of my intercession. Bukhari transmitted it.

‘Abdallah b. Mughaffal reported God’s Messenger as saying, “Between every pair of adhans there is a prayer; between every pair of adhans there is a prayer.” Then he said on repeating it a third time, “for him who wishes.” (Bukhari and Muslim.)

Ibn ‘Umar reported God’s Messenger as saying, “Bilal summons to prayer when it is still night, so eat and drink till Ibn Umm Maktum makes the summons.” He added that Ibn Umm Maktum was a blind man who did not make the summons till someone said to him, “The morning has come, the morning has come.” (Bukhari and Muslim.)

He also told of God's Messenger saying to them, “Pray as you have seen me prayer, and when the time for prayer comes one of you should call the adhan for you and the oldest of you should act as imam.”* * In this tradition the plural is used throughout; in the preceding the dual is used, two persons being referred to. (Bukhari and Muslim.)

Abu Huraira said that when God’s Messenger returned from the expedition to Khaibar,1 he travelled one night and stopped for rest only when he became sleepy. He told Bilal to remain on guard during the night, and he prayed as much as he could while God’s Messenger and his companions slept. When the time for dawn approached Bilal leaned on his camel facing in the direction from which the dawn should appear; but he was overcome by sleep while he was leaning on his camel, and neither God’s Messenger nor Bilal awoke, nor did any of his companions till the sun shone on them. God's Messenger was the first of them to awake, and being startled he called to Bilal, who said "He who took away my soul is the One who took away yours."2 He said, "Lead the beasts on,” and when they had done so for some distance, God’s Messenger performed ablution, gave orders to Bilal who pronounced the iqama, and then led them in the Morning Prayer. When he finished the prayer he said, "If anyone forgets prayer he should say it when he remembers it, for God has said, ‘And observe the prayer for remembrance of me.’”3 1. In 7 AH. 2. This is probably to be connected with the thought in the Qur’an, 39:42, which speaks of God taking the souls of people during their sleep. 3. Al-Qur’an; 20:14 Muslim transmitted it.

Abu Qatada reported God’s Messenger as saying, "When the iqama is pronounced, do not get up till you see I have come out.” (Bukhari and Muslim.)

Abu Huraira reported God’s Messenger as saying, "When the iqama has been pronounced for prayer, do not go running to it, but go walking in tranquility, and pray what you are in time for and complete what you have missed.” (Bukhari and Muslim.) A version by Muslim has, "for when one of you is making for prayer he is engaged in prayer.”

Ibn ‘Abbas said that when the Prophet (ﷺ) entered the House (the Ka’ba) he made supplications in all sides of it, but did not perform salat till he had come out. When he came out he prayed two rak'as facing the Ka'ba and said, “This is the qibla.” Bukhari transmitted it and Muslim transmitted it from Ibn ‘Abbas from Usama b. Zaid.

‘Abdallah b. ‘Umar said: God's Messenger entered the Ka'ba with Usama b. Zaid, ‘Uthman b. Talha al-Hajabi, and Bilal b. Rabah, and locking it behind him, he remained inside. I asked Bilal when he came out what God's Messenger had done, and he said, “He took up a position with one pillar on his left, two on his right, and three behind him (the House at that time having six pillars), then performed salat.” (Bukhari and Muslim.)

Abu Huraira reported God’s Messenger as saying, “One prayer in this mosque of mine (i.e. the mosque in Medina) is better than a thousand elsewhere, except the sacred mosque.” (Bukhari and Muslim)

Abu Sa'id al-Khudri reported God’s Messenger as saying, “Animals are saddled only for prayer in the three mosques: the sacred mosque, the Aqsa mosque, and this mosque of mine.”* * These are the only mosques to which long journeys may be made purely for the purpose of praying in them. The sacred mosque means the Ka'ba. (Bukhari and Muslim.)

Abu Huraira reported God's Messenger as saying, “The space between my house and my pulpit is one of the gardens of paradise, and my pulpit is upon my tank.” (Bukhari and Muslim.)

Ibn ‘Umar said that the Prophet (ﷺ) used to go to the mosque in Quba'* every Saturday, walking and riding, and he would pray two rak'as in it. * The village outside Medina where the Prophet (ﷺ) stayed a few days before entering Medina at the time of the Hijra. Before leaving he laid the foundations of a mosque there. Al-Qur’an; 9:108 is said to refer to this mosque. In the preceding verse reference is made to another mosque which had been built in a spirit of opposition. (Bukhari and Muslim.)

‘Uthman reported God's Messenger as saying, “If anyone builds a mosque for God, God will build a house for him in paradise.” (Bukhari and Muslim.)

Abu Huraira reported God’s Messenger as saying, “If anyone goes out in the morning or in the evening to the mosque, God will prepare for him his food in paradise as often as he goes out in the morning or in the evening.” (Bukhari and Muslim.)

Abu Musa reported God’s Messenger as saying, “The one who will receive the greatest reward for prayer is he who lives farthest away, and he who has farthest to walk and he who waits for the prayer to observe it with the imam will have a greater reward than the one who observes it and then goes to sleep.” (Bukhari and Muslim.)

Abu Huraira reported God’s Messenger as saying, “There are seven whom God will cover with His shade on the day when there will be no shade but His: a just imam; a young man who grows up worshipping God; a man whose heart is attached to the mosque from the time he leaves it till he returns to it; two men who love one another for God's sake, meeting thus and separating thus; a man who remembers God in solitude, his eyes pouring forth tears; a man who, when accosted by a woman of rank and beauty, says, ‘I fear God’; and a man who gives alms concealing it so that his left hand does not know what his right hand bestows.” (Bukhari and Muslim.)

He also reported God’s Messenger as saying, “A man's prayer in company is twenty-five times as valuable as his prayer in his house and his market, for when he performs ablution, doing it well, then goes out to the mosque, having no other reason than prayer for going out, he does not take a step without being raised a degree for it and having a sin remitted for it, and when he prays the angels continue to invoke blessings on him as long as he is in his place of prayer, saying, ‘God bless him; God show mercy to him.’ And each of you continues to be engaged in prayer as long as he is waiting for the prayer.” In a version he said, “When he enters the mosque prayer holds him fast.” And he added in the invocation of the angels, “O God, forgive him, O God, turn towards him, as long as he does not do any harm in it and as long as he does not do anything unseemly in it.” (Bukhari and Muslim.)
