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."

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, "If anyone of you, when having sexual intercourse with his wife, says: Bismillah, Allahumma jannibni-Sh-Shaitan wa jannib-ish-Shaitan ma razaqtana, and if it is destined that they should have a child, then Satan will never be able to harm him."

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."

The Prophet beckoned with his hand towards Yemen and said, "Belief is there." The harshness and mercilessness are the qualities of those farmers etc, who are busy with their camels and pay no attention to the religion (is towards the east) from where the side of the head of Satan will appear; those are the tribes of Rabi`a and Mudar.

(the wife of the Prophet) That she came to visit Allah's Apostle while he was in I`tikaf (i.e. seclusion in the Mosque during the last ten days of Ramadan). When she got up to return, Allah's Apostle got up with her and accompanied her, and when he reached near the gate of the Mosque close to the door (of the house) of Um Salama, the wife of the Prophet, two Ansari men passed by them and greeted Allah's Apostle and then went away. Allah's Apostle addressed them saying, "Don't hurry! (She is my wife)," They said, "Glorified be Allah! O Allah's Apostle (You are far away from any suspicion)," and his saying was hard on them. Allah's Apostle said, "Satan circulates in the mind of a person as blood does (in his body). I was afraid that Satan might put some (evil) thoughts in your minds."

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."

Allah's Apostle said, "Satan comes to one of you and says, 'Who created so-and-so? 'till he says, 'Who has created your Lord?' So, when he inspires such a question, one should seek refuge with Allah and give up such thoughts."

Allah's Apostle said, "When anyone of you stands for the prayers, Satan comes and puts him in doubts till he forgets how many rak`at he has prayed. So if this happens to anyone of you, he should perform two prostrations of Sahu while sitting.

The Prophet pointed with his hand towards Yemen and said twice, "Faith is there," and then pointed towards the East, and said, "Verily, sternness and mercilessness are the qualities of those who are busy with their camels and pay no attention to their religion, where the two sides of the head of Satan will appear," namely, the tribes of Rabl'a and Muqar.

Allah's Apostle said, "If anyone of you, when intending to have a sexual relation (sleep) with his wife, says: Bismillah, Allahumma jannibna ashShaitan, wa Jannib ash-Shaitana ma razaqtana, Satan would never harm that child, should it be ordained that they will have one. (Because of that sleep).

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."

Allah's Apostle said, "When night falls (or it is evening), keep your children close to you for the devils spread out at that time. But when an hour of the night elapses, you can let them free. Close the doors and mention the Name of Allah, for Satan does not open a closed door."

The Prophet said, "If anyone of you, when intending to have a sexual intercourse with his wife, says: 'Bismillah, Allahumma jannibna-sh-shaitan, wa jannibi-sh-shaitan ma razaqtana,' and if the couple are destined to have a child (out of that very sexual relation), then Satan will never be able to harm that child."

Safiya, the wife of the Prophet told me that she went to Allah's Apostle to visit him in the mosque while he was in I`tikaf in the last ten days of Ramadan. She had a talk with him for a while, then she got up in order to return home. The Prophet accompanied her. When they reached the gate of the mosque, opposite the door of Um-Salama, two Ansari men were passing by and they greeted Allah's Apostle . He told them: Do not run away! And said, "She is (my wife) Safiya bint Huyai." Both of them said, "Subhan Allah, (How dare we think of any evil) O Allah's Apostle!" And they felt it. The Prophet said (to them), "Satan reaches everywhere in the human body as blood reaches in it, (everywhere in one's body). I was afraid lest Satan might insert an evil thought in your minds."

The wife of the Prophet that she went to Allah's Apostle while he was in I`tikaf (staying in the mosque) during the last ten nights of the month of Ramadan. She spoke to him for an hour (a while) at night and then she got up to return home. The Prophet got up to accompany her, and when they reached the gate of the mosque opposite the dwelling place of Um Salama, the wife of the Prophet, two Ansari men passed by, and greeting Allah's Apostle , they quickly went ahead. Allah's Apostle said to them, "Do not be in a hurry She is Safiya, the daughter of Huyai." They said, "Subhan Allah! O Allah's Apostle (how dare we suspect you)." That was a great thing for both of them. The Prophet then said, "Satan runs in the body of Adam's son (i.e. man) as his blood circulates in it, and I was afraid that he (Satan) might insert an evil thought in your hearts."

The Prophet and I walked till we reached the dumps of some people. He stood, as any one of you stands, behind a wall and urinated. I went away, but he beckoned me to come. So I approached him and stood near his back till he finished.

Gabriel did not come to the Prophet (for some time) and so one of the Quraish women said, "His Satan has deserted him." So came the Divine Revelation: "By the forenoon And by the night When it is still! Your Lord (O Muhammad) has neither Forsaken you Nor hated you." (93.1-3)

The son of Abu Said al-Khudri reported on the authority of his father that Allah's Messenger (may peace be upon him) said. When one of you yawns while engaged in prayer, he should try to restrain so far as it lies in his power, since it is the Satan that enter therein.

AbdurRahman ibn Hasanah reported: I and Amr ibn al-'As went to the Prophet (saws). He came out with a leather shield (in his hand). He covered himself with it and urinated. Then we said: Look at him. He is urinating as a woman does. The Prophet (saws), heard this and said: Do you not know what befell a person from amongst Banu Isra'il (the children of Israel)? When urine fell on them, they would cut off the place where the urine fell; but he (that person) forbade them (to do so), and was punished in his grave.

Abu Dawud said: One version of Abu Musa has the wording: "he cut off his skin".

Another version of Abu Musa goes: "he cut off (part of) his body."

A Bedouin stood up and started making water in the mosque. The people caught him but the Prophet ordered them to leave him and to pour a bucket or a tumbler of water over the place where he had passed the urine. The Prophet then said, "You have been sent to make things easy and not to make them difficult."

I brought my young son, who had not started eating (ordinary food) to Allah's Apostle who took him and made him sit in his lap. The child urinated on the garment of the Prophet, so he asked for water and poured it over the soiled (area) and did not wash it.

(The Prophet) said, "O Allah! Bless our Sham and our Yemen." People said, "Our Najd as well." The Prophet again said, "O Allah! Bless our Sham and Yemen." They said again, "Our Najd as well." On that the Prophet said, "There will appear earthquakes and afflictions, and from there will come out the side of the head of Satan."

I went to Sham (and asked. "Who is here?"), The people said, "Abu Ad-Darda." Abu Darda said, "Is the person whom Allah has protected against Satan, (as Allah's Apostle said) amongst you". The subnarrator, Mughira said that the person who was given Allah's Refuge through the tongue of the Prophet was `Ammar (bin Yasir).

I heard the Prophet saying, "A good dream is from Allah, and a bad dream is from Satan. So if anyone of you sees (in a dream) something he dislikes, when he gets up he should blow thrice (on his left side) and seek refuge with Allah from its evil for then it will not harm him."

as below.

Narrated Abu Qatada:

The Prophet said, "A good dream is from Allah, and a bad or evil dream is from Satan; so if anyone of you has a bad dream of which he gets afraid, he should spit on his left side and should seek Refuge with Allah from its evil, for then it will not harm him."

(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."
