Narrated `Aisha: Magic was worked on the Prophet so that he began to fancy that he was doing a thing which he was not actually doing. One day he invoked (Allah) for a long period and then said, "I feel that Allah has inspired me as how to cure myself. Two persons came to me (in my dream) and sat, one by my head and the other by my feet. One of them asked the other, "What is the ailment of this man?" The other replied, 'He has been bewitched" The first asked, 'Who has bewitched him?' The other replied, 'Lubaid bin Al-A'sam.' The first one asked, 'What material has he used?' The other replied, 'A comb, the hair gathered on it, and the outer skin of the pollen of the male date-palm.' The first asked, 'Where is that?' The other replied, 'It is in the well of Dharwan.' " So, the Prophet went out towards the well and then returned and said to me on his return, "Its date-palms (the date-palms near the well) are like the heads of the devils." I asked, "Did you take out those things with which the magic was worked?" He said, "No, for I have been cured by Allah and I am afraid that this action may spread evil amongst the people." Later on the well was filled up with earth.

Narrated Abu Huraira: Allah's Apostle 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 gay, otherwise he gets up dull and gloomy. "

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

Narrated Ibn `Abbas: The Prophet 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."

Narrated Ibn `Umar: Allah's Apostle 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).

Narrated Abu Said Al-Khudri: 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."

Narrated Muhammad bin Sirin: Abu Huraira said, "Allah's Apostle 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 Apostle." 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 said, "He told you the truth, though he is a liar, and he (the thief) himself was the Satan."

Narrated Abu Huraira: 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."
