Allah's Messenger (ﷺ) said, "During your sleep, Satan knots three knots at the back of the head of each of you, and he breathes the following words at each knot, 'The night is, long, so keep on sleeping,' If that person wakes up and celebrates the praises of Allah, then one knot is undone, and when he performs ablution the second knot is undone, and when he prays, all the knots are undone, and he gets up in the morning lively and in good spirits, otherwise he gets up in low spirits and lethargic."

It was mentioned before the Prophet (ﷺ) that there was a man who slept the night till morning (after sunrise). The Prophet (ﷺ) said, "He is a man in whose ears (or ear) Satan had urinated."

The Prophet (ﷺ) said, "If anyone of you, when having sexual relation with his wife, say: 'In the name of Allah. O Allah! Protect us from Satan and prevent Satan from approaching our offspring you are going to give us,' and if he begets a child (as a result of that relation) Satan will not harm it."

Allah's Messenger (ﷺ) said, "When the (upper) edge of the sun appears (in the morning), don't perform a prayer till the sun appears in full, and when the lower edge of the sun sets, don't perform a prayer till it sets completely. And you should not seek to pray at sunrise or sunset for the sun rises between two sides of the head of the devil (or Satan).

The Prophet (ﷺ) 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."

Abu Huraira said, "Allah's Messenger (ﷺ) put me in charge of the Zakat of Ramadan (i.e. Zakat-ul-Fitr). Someone came to me and started scooping some of the foodstuff of (Zakat) with both hands. I caught him and told him that I would take him to Allah's Messenger (ﷺ)." Then Abu Huraira told the whole narration and added "He (i.e. the thief) said, 'Whenever you go to your bed, recite the Verse of "Al-Kursi" (2.255) for then a guardian from Allah will be guarding you, and Satan will not approach you till dawn.' " On that the Prophet (ﷺ) said, "He told you the truth, though he is a liar, and he (the thief) himself was the Satan."

Allah's Messenger (ﷺ) 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 Messenger (ﷺ) said, "When the month of Ramadan comes, the gates of Paradise are opened and the gates of the (Hell) Fire are closed, and the devils are chained."

That he heard Allah's Messenger (ﷺ) saying, "(The prophet) Moses said to his attendant, "Bring us our early meal' (18.62). The latter said, 'Did you remember when we betook ourselves to the rock? I indeed forgot the fish and none but Satan made me forget to remember it." (18.63) Moses did not feel tired till he had crossed the place which Allah ordered him to go to."

I saw Allah's Messenger (ﷺ) pointing towards the east saying, "Lo! Afflictions will verily emerge hence; afflictions will verily emerge hence where the (side of the head of) Satan appears."

The Prophet (ﷺ) said, "When nightfalls, then keep your children close to you, for the devil spread out then. An hour later you can let them free; and close the gates of your house (at night), and mention Allah's Name thereupon, and cover your utensils, and mention Allah's Name thereupon, (and if you don't have something to cover your utensil) you may put across it something (e.g. a piece of wood etc.).

While Allah's Messenger (ﷺ) was in I`tikaf, I called on him at night and having had a talk with him, I got up to depart. He got up also to accompany me to my dwelling place, which was then in the house of Usama bin Zaid. Two Ansari men passed by, and when they saw the Prophet (ﷺ) they hastened away. The Prophet said (to them). "Don't hurry! It is Safiya, the daughter of Huyay (i.e. my wife)." They said, "Glorified be Allah! O Allah's Messenger (ﷺ)! (How dare we suspect you?)" He said, "Satan circulates in the human mind as blood circulates in it, and I was afraid that Satan might throw an evil thought (or something) into your hearts."

While I was sitting in the company of the Prophet, two men abused each other and the face of one of them became red with anger, and his jugular veins swelled (i.e. he became furious). On that the Prophet said, "I know a word, the saying of which will cause him to relax, if he does say it. If he says: 'I seek Refuge with Allah from Satan.' then all is anger will go away." Some body said to him, "The Prophet has said, 'Seek refuge with Allah from Satan."' The angry man said, "Am I mad?"

The Prophet (ﷺ) said, "If anyone of you, on having sexual relation with his wife, says: 'O Allah! Protect me from Satan, and prevent Satan from approaching the offspring you are going to give me,' and if it happens that the lady conceives a child, Satan will neither harm it nor be given power over it."

The Prophet (ﷺ) offered a prayer, and (after finishing) he said, "Satan came in front of me trying persistently to divert my attention from the prayer, but Allah gave me the strength to over-power him."

The Prophet (ﷺ) 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).

The Prophet (ﷺ) said, "When any human being is born. Satan touches him at both sides of the body with his two fingers, except Jesus, the son of Mary, whom Satan tried to touch but failed, for he touched the placenta-cover instead."

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 Messenger (ﷺ) 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).

The Prophet (ﷺ) said, "While the angels talk amidst the clouds about things that are going to happen on earth, the devils hear a word of what they say and pour it in the ears of a soothsayer as one pours something in a bottle, and they add one hundred lies to that (one word).

The Prophet (ﷺ) said, "Yawning is from Satan and if anyone of you yawns, he should check his yawning as much as possible, for if anyone of you (during the act of yawning) should say: 'Ha', Satan will laugh at him."
