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."

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 Messenger of Allah (saws) said: These privies are frequented by the jinns and devils. So when anyone amongst you goes there, he should say: "I seek refuge in Allah from male and female devils."

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.

(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 Prophet said, "If while you are praying, somebody intends to pass in front of you, prevent him; and should he insist, prevent him again; and if he insists again, fight with him (i.e. prevent him violently e.g. pushing him violently), because such a person is (like) a devil."

The Prophet said, "Name yourselves after me (by my name), but do not call yourselves by my Kuniya, and whoever sees me in a dream, he surely sees me, for Satan cannot impersonate me (appear in my figure). And whoever intentionally ascribes something to me falsely, he will surely take his place in the (Hell) Fire.

(a companion of the Prophet and one of his cavalry men) "I heard Allah's Apostle saying, "A good dream is from Allah, and a bad dream is from Satan; so, if anyone of you had a bad dream which he disliked, then he should spit on his left and seek refuge with Allah from it, for it will not harm him."

Safiya bint (daughter of) Huyai came to the Prophet (in the mosque), and when she returned (home), the Prophet accompanied her. It happened that two men from the Ansar passed by them and the Prophet called them saying, "She is Safiya!" those two men said, "Subhan Allah!" The Prophet said, "Satan circulates in the human body as blood does."

Abu Bakr came to my house while two small Ansari girls were singing beside me the stories of the Ansar concerning the Day of Buath. And they were not singers. Abu Bakr said protestingly, "Musical instruments of Satan in the house of Allah's Apostle !" It happened on the `Id day and Allah's Apostle said, "O Abu Bakr! There is an `Id for every nation and this is our `Id."

A drunk was brought to the Prophet and he ordered him to be beaten (lashed). Some of us beat him with our hands, and some with their shoes, and some with their garments (twisted in the form of a lash). When that drunk had left, a man said, "What is wrong with him? May Allah disgrace him!" Allah's Apostle said, "Do not help Satan against your (Muslim) brother."

The Prophet said, "If anyone of you sees a dream that he likes, then it is from Allah, and he should thank Allah for it and narrate it to others; but if he sees something else, i.e., a dream that he dislikes, then it is from Satan, and he should seek refuge with Allah from its evil, and he should not mention it to anybody, for it will not harm him."

The Prophet used to seek Refuge with Allah for Al-Hasan and Al-Husain and say: "Your forefather (i.e. Abraham) used to seek Refuge with Allah for Ishmael and Isaac by reciting the following: 'O Allah! I seek Refuge with Your Perfect Words from every devil and from poisonous pests and from every evil, harmful, envious eye.' "

The Prophet said, "Name yourselves with my name (use my name) but do not name yourselves with my Kunya name (i.e. Abul Qasim). And whoever sees me in a dream then surely he has seen me for Satan cannot impersonate me. And whoever tells a lie against me (intentionally), then (surely) let him occupy his seat in Hell-fire."

Allah's Apostle pointed with his hand towards Yemen and said, "(True) Belief is Yemenite, towards here (i.e. the Yemenite, had True Belief and embraced Islam readily). Certainly sternness and mercilessness are the qualities of those who are loud and at the base of the tails of camels, where the two horns of Satan will appear. Such qualities belong to the tribes of Rabi`a and Mudar."

I heard Allah's Apostle saying, "If anyone of you saw a dream which he liked, then that was from Allah, and he should thank Allah for it and tell it to others; but if he saw something else, i.e, a dream which he did not like, then that is from Satan and he should seek refuge with Allah from it and should not tell it to anybody for it will not harm him."

That once Abu Bakr came to her on the day of `Id-ul-Fitr or `Id ul Adha while the Prophet was with her and there were two girl singers with her, singing songs of the Ansar about the day of Buath. Abu Bakr said twice. "Musical instrument of Satan!" But the Prophet said, "Leave them Abu Bakr, for every nation has an `Id (i.e. festival) and this day is our `Id."

Once the Prophet fell ill and did not offer the night prayer (Tahajjud prayer) for a night or two. A woman (the wife of Abu Lahab) came to him and said, "O Muhammad ! I do not see but that your Satan has left you." Then Allah revealed (Surat-Ad-Duha): 'By the fore-noon, and by the night when it darkens (or is still); Your Lord has not forsaken you, nor hated you.' (93)

Abu Huraira said, "A man who drank wine was brought to the Prophet. The Prophet said, 'Beat him!" Abu Huraira added, "So some of us beat him with our hands, and some with their shoes, and some with their garments (by twisting it) like a lash, and then when we finished, someone said to him, 'May Allah disgrace you!' On that the Prophet said, 'Do not say so, for you are helping Satan to overpower him.' "
