Ibn ‘Umar reported God’s Messenger as saying, “Perform some of your prayer in your houses, and do not turn them into graves.”* * This is most probably a figurative expression indicating that a house in which prayer is not offered is like a grave, as God is not worshipped there.(Bukhari and Muslim.)

Talq b. ‘Ali said; we went out as a deputation to God’s Messenger and swore allegiance to him and prayed along with him. We told him that we had a church in our land, and we asked him for some of the leavings of the water he used for ablution. He called for water, performed ablution, rinsed his mouth, then poured it out for us into a skin vessel, and gave us the following command, “Go away, and when you come to your land break down your church, sprinkle this water on its site, and use it as a mosque." We told him that our land was distant, the heat severe, and that the water would evaporate, to which he replied, “Add some water to it, for it will only bring more good to it.”Nasa'i transmitted it.

Al-Qur’an, 20:126.Tirmidhi and Abu Dawud transmitted it.

Buraida reported God's Messenger as saying, “Announce to those who make a practice of walking to mosques during the times of darkness the good news that they will have complete light on the day of resurrection. Tirmidhi and Abu Dawud transmitted it, and Ibn Majah transmitted it from Sahl b. Sa'd and Anas.

‘Uthman b. Mazun said, “Messenger of God, grant us permission to become eunuchs." God’s Messenger replied, “He who makes another a eunuch or becomes one himself does not belong to us; fasting serves that purpose among my people." He then said, "Grant us permission to lead the wandering life of the devotee." He replied, "The wandering life of the devotee among my people is jihad in God’s path." He said, "Grant us permission to adopt monkery.” He replied, "Monkery among my people consists of sitting in mosques waiting for the time of prayer." Baghawi transmitted it in Sharh as-sunna.

He asked, "Muhammad, do you know what the angels near My presence dispute about?" I replied, "Yes, about expiations, and they are remaining in the mosques after the prayers are over, walking on foot to the congregational prayers, and performing elaborate ablution in unpleasant circumstances (Cf. p. 151). Whoever does that will live and die righteously, and as far as his sin is concerned, he will be as he was on the day his mother gave birth to him." He said, "Muhammad, when you pray say, ‘O God, I ask Thee to enable me to do good deeds, abandon objectionable things, and love the poor, and when Thou intendest to test Thy servants, take me to Thyself without being led astray.'" He said, "People are raised in degree by saluting all and sundry, providing food, and praying at night when people are asleep." The wording of this tradition is as it occurs in al-Masabih, but I found it traced to ‘Abd ar-Rahman only in Sharh as-sunna.

Shaddad b. Aus reported God’s Messenger as saying, “Act differently from the Jews, for they do not pray in their sandals or their shoes.”* * Khuff (pl. khifaf), an article of footwear which came up above the ankle. Traditions tell that the Prophet allowed pilgrims to wear the khuff only when unable to procure sandals, but said they must be cut to come below the ankle. Cf. Bukhari, Hajj, 21, 23; Libas, 8, 4, 15, 73.Abu Dawud transmitted it.

Abu Juhaifa said, “I saw God's Messenger in Mecca at al-Abtah in a red leather tent, I saw Bilal take the ablution water left by God’s Messenger, and I saw the people racing one another to get to that ablution water. If anyone got any of it he rubbed himself with it, and anyone who did not get any got some of the moisture from his companion’s hand. I then saw Bilal take a staff and fix it in the ground, after which God’s Messenger came out quickly in a red mantle and led the people in two rak'as facing the staff. And I saw people and animals passing in front of the staff.” (Bukhari and Muslim.)

I passed in front of part of the row of worshippers, and dismounting, let my she-ass go to pasture and joined the row, and no one objected to that.” (Bukhari and Muslim.)
