Abu Huraira said that he heard God’s messenger say, “Perform ablution because of anything which has been touched by fire.” Muslim transmitted it.

(Bukhari and Muslim.)

Jabir b. Samura said that a man asked God’s messenger whether they should perform ablution after eating mutton and he replied, “You may perform ablution or not, as you wish.” He asked if they should perform ablution after eating camel flesh and he replied, “Yes, perform ablution after eating camel flesh.” He then asked whether he might say prayers in sheepfolds and he replied, “Yes”; but when he asked whether he might say prayers in places where camels lie down, he replied, “No.”Muslim transmitted it.

Abu Huraira reported God’s messenger as saying, “If any of you has a pain in his abdomen, but is doubtful whether or not anything has issued from him, he should not leave the mosque unless he hears a sound or perceives a smell.” Muslim transmitted it.

Suwaid b. an-Nu‘man said that he went out with God’s messenger in the year of Khaibar [Khaibar was taken in 7 A.H.], and when they were at as-Sahba’ which is very near Khaibar, he prayed the afternoon prayer. He then called for food, and when only some flour was produced, he ordered it to be moistened;then God’s messenger and the company ate. After that he got up to pray the sunset prayer, and when he and the company had rinsed their mouths he prayed without performing ablution. Bukhari transmitted it.

He also reported God's messenger as saying, “The key of prayer is purification, saying ‘God is most great’ makes it a sacred state, and the salutation brings the sacred state to an end.” Abu Dawud, Tirmidhi and Darimi transmitted it, and Ibn Majah transmitted it both from 'Ali and from Abu Sa'id.

Abu Dawud transmitted it, and the shaikh and imam Muhyi as-Sunna said that this does not refer to one who is sitting because of the sound tradition from Anas who said that the Companions of God’s messenger dozed while waiting for nightfall, then prayed without performing ablution. Abu Dawud and Tirmidhi transmitted it, but Tirmidhi said “they slept” instead of saying that they “dozed while waiting for nightfall.”

Talq b. ‘Ali said that God’s messenger was asked about a man touching his penis after performing ablution, and replied, “What is it but a part of him?” Abu Dawud, Tirmidhi and Nasa’i transmitted it, and Ibn Majah transmitted something similar. The shaikh and imamMuhyi as-Sunna said that this is abrogated because Abu Huraira accepted Islam after Talq came, and Abu Huraira has transmitted from God’s messenger the saying, “If anyone touches his penis with his hand, nothing coming between them, he must perform ablution.”Shafi‘i and Daraqutni transmitted it, and Nasa’i transmitted it from Busra, but did not include “nothing between them.”

‘A’isha said that the Prophet used to kiss one of his wives and then pray without performing ablution. Abu Dawud, Tirmidhi, Nasa’i and Ibn Majah transmitted it.
