Muhammad b. Ibrahim on the authority of Qais b. ‘Amr told how when the prophet saw a man praying two rak'as after the Morning Prayer he said, “At the Morning Prayer pray two rak'as." The man replied I had not prayed the two rak'as which precede them, so I prayed themjust now,” and God’s Messenger said nothing. Abu Dawud transmitted it. Tirmidhi transmitted something similar, saying, “The isnad of this tradition is not connected, because Muhammad b. Ibrahim did not hear from Qais b. ‘Amr.” There is something similar in Sharh as-sunna and in some texts of al-Masabih from Qais b. Qahd.

‘Abdallah as-Sunabihi reported God’s Messenger as saying, “The sun rises accompanied by the horn of the devil, but when it is fully risen it leaves it; then when it is at the meridian it joins it, but when it passes the meridian it leaves it; then when it comes near to setting it joins it, but when it sets it leaves it.” God’s Messenger prohibited prayer at those hours. Malik, Ahmad and Nasa’i transmitted it.

He reported God’s Messenger as saying, “When one of you is served with his supper and the time for prayer comes, he should first have his supper and not hasten till he has finished it.” When Ibn ‘Umar’s food was served and the time for prayer came, he did not go to the prayer till he finished it; and he could hear the imam’s recitation. (Bukhari and Muslim.)

God’s Messenger led us in the dawn prayer one day, and when he gave the salutation he asked, “Is so and so present?” and was told that he was not. He asked, “Is so and so present?” and was told that he was not. He then said, “These two prayers* are the ones which are most burdensome to hypocrites. If you knew the blessings they contain you would come to them, even though you had to crawl on your knees. The first row is like that of the angels, and if you knew the nature of its excellence you would race to join it. A man’s prayer said along with another is purer than his prayer said alone, and his prayer with two men is purer than his prayer with one, but if there are more it is more pleasing to God.” *i.e. the evening prayer and the dawn prayer.Abu Dawud and Nasa’i transmitted it.

Abud Darda’ reported God’s Messenger as saying, “If there are three men in a village or in the desert among whom prayer is not arranged, the devil has got the mastery over them. So observe prayer in company, for the wolf eats only the straggling animal.” Ahmad, Abu Dawud and Nasa’i transmitted it.

Ibn ‘Abbas reported God’s Messenger as saying, “If any one hears him who makes the call to prayer and is not prevented from joining the congregation by any excuse,” (he was asked what an excuse consisted of and replied that it was fear or illness), “the prayer he says will not be accepted from him.” Abu Dawud and Daraqutni transmitted it.

‘Uthman b. ‘Affan reported God’s Messenger as saying, “If the adhan is called when anyone is in the mosque and he goes out for any other reason than some necessary purpose, not intending to return, he is a hypocrite.” Ibn Majah transmitted it.

Abu Bakr b. Sulaiman b. Abu Hathma said that ‘Umar b. al-Khattab missed Sulaiman b. Abu Hathma at the Morning Prayer. In the morning ‘Umar went to the market, and Sulaiman’s house being between the mosque and the market, he met ash-Shifa’, Sulaiman’s mother, and said to her, “I did not see Sulaiman at the morning prayer.” She replied, “He spent the night in prayer and was overpowered by sleep.” Thereupon ‘Umar said, “I would rather be present with a company at the Morning Prayer than spend a night in prayer.” Malik transmitted it.

‘Abdallah confronted him, and reviling him in terms the like of which I have never heard at any other time, he said, “I give you information on the authority of God’s Messenger, yet you say, ‘I swear by God I will certainly prevent them’!” * He is Salim b. ‘Abdallah b. ‘Umar b. al-Khattab.Muslim transmitted it.

The iqama* had been uttered and God’s Messenger faced us and said, “Make your rows straight and stand close together, for l can see you behind my back.” * A repetition of the words of the call to prayer after the worshippers have taken their places with the addition of a statement that the time of prayer has come.Bukhari transmitted it. In the version given by Bukhari and Muslim he said, “Make the rows perfect, for I can see you behind my back."
