Allah's Apostle said, "The prayer of a person who does Hadath (passes urine, stool or wind) is not accepted till he performs the ablution." A person from Hadaramout asked Abu Huraira, "What is 'Hadath'?" Abu Huraira replied, " 'Hadath' means the passing of wind."

Allah's Apostle said, "A person is considered in prayer as long as he is waiting for the prayer in the mosque as long as he does not do Hadath." A non-Arab man asked, "O Abu Huraira! What is Hadath?" I replied, "It is the passing of wind (from the anus) (that is one of the types of Hadath).

The Prophet said, "Allah does not accept prayer of anyone of you if he does Hadath (passes wind) till he performs the ablution (anew).

Um Sulaim said, "O Allah's Apostle! Verily Allah is not shy of (telling you) the truth. Is it essential for a woman to take a bath after she had a wet dream (nocturnal sexual discharge)?" He said, "Yes, if she notices discharge. On that Um Salama laughed and said, "Does a woman get a (nocturnal sexual) discharge?" He said, "How then does (her) son resemble her (his mother)?"

Allah's Apostle said, "The angels keep on asking Allah's forgiveness for anyone of you, as long as he is at his Musalla (praying place) and he does not pass wind (Hadath). They say, 'O Allah! Forgive him, O Allah! be Merciful to him."

Um Sulaim came to Allah's Apostle and said, "O Allah's Apostle! Verily, Allah does not feel shy to tell the truth. If a woman gets a nocturnal sexual discharge (has a wet dream), is it essential for her to take a bath? He replied, "Yes if she notices a discharge."

(the mother of the believers) Um Sulaim, the wife of Abu Talha, came to Allah's Apostle and said, "O Allah's Apostle! Verily Allah is not shy of (telling you) the truth. Is it necessary for a woman to take a bath after she has a wet dream (nocturnal sexual discharge)?" Allah's Apostle replied, "Yes, if she notices a discharge."

Allah's Apostle said, "The angels keep on asking for Allah's Blessing and Forgiveness for anyone of you as long as he is at his Musalla (praying place) and does not do Hadath (passes wind). The angels say, 'O Allah! Forgive him and be Merciful to him.' Each one of you is in the prayer as long as he is waiting for the prayer and nothing but the prayer detains him from going to his family."

Anas said, "The Prophet used to perform ablution for every prayer." I asked Anas, "What did you used to do?' Anas replied, "We used to pray with the same ablution until we break it with Hadath."

Allah's Apostle said, "When you drink (water), do not breath in the vessel; and when you urinate, do not touch your penis with your right hand. And when you cleanse yourself after defecation, do not use your right hand."

Um-Sulaim came to Allah's Apostle and said, "Verily, Allah is not shy of (telling you) the truth. Is it necessary for a woman to take a bath after she has a wet dream (nocturnal sexual discharge?) The Prophet replied, "Yes, if she notices a discharge." Um Salama, then covered her face and asked, "O Allah's Apostle! Does a woman get a discharge?" He replied, "Yes, let your right hand be in dust (An Arabic expression you say to a person when you contradict his statement meaning "you will not achieve goodness"), and that is why the son resembles his mother."

The Prophet (saws) said: None amongst you should urinate in standing water, then wash in it after sexual defilement.

Allah's Apostle said, "The first group of people who will enter Paradise, will be glittering like the full moon and those who will follow them, will glitter like the most brilliant star in the sky. They will not urinate, relieve nature, spit, or have any nasal secretions. Their combs will be of gold, and their sweat will smell like musk. The aloes-wood will be used in their centers. Their wives will be houris. All of them will look alike and will resemble their father Adam (in stature), sixty cubits tall."

The Prophet (saws) had a wooden vessel under his bed in which he would urinate at night.

Usama b. Zaid (Allah be pleased with him) reported that he sat behind Allah's Messenger (may peace be upon him) on his ride as he came back from 'Arafa. And as he came to the valley, he halted his camel, and then went to the wilderness (to urinate). And when he came back, I poured water on him from the jug and he performed ablution, and then rode on until he came to Muzdalifa and there he combined the sunset and 'Isha' prayers.

The Prophet (saws) prohibited to urinate in a hole.

Qatadah (a narrator) was asked about the reason for the disapproval of urinating in a hole. He replied: It is said that these (holes) are the habitats of the jinn.

The Prophet said, "When the call for the prayer is pronounced, Satan takes to his heels, passing wind with noise, When the call for the prayer is finished, he comes back. And when the Iqama is pronounced, he again takes to his heels, and after its completion, he returns again to interfere between the (praying) person and his heart, saying to him. 'Remember this or that thing.' till the person forgets whether he has offered three or four rak`at: so if one forgets whether he has prayed three or four rak`at, he should perform two prostrations of Sahu (i.e. forgetfulness).

Allah's Apostle said, "When the call for prayer is made, Satan takes to his heels passing wind so that he may not hear the Adhan and when the call is finished he comes back, and when the Iqama is pronounced, Satan again takes to his heels, and when the Iqama is finished he comes back again and tries to interfere with the person and his thoughts and say, "Remember this and that (which he has not thought of before the prayer)", till the praying person forgets how much he has prayed. If anyone of you does not remember whether he has offered three or four rak`at then he should perform two prostrations of Sahu while sitting.
