Satan ties knots in your head while you sleep -- Sahih Buhari-- Volume 4, Book 54, Number 491:
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. "

Sahih Al-Bukhari Hadith - 4.490
 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.
  Sahih Muslim Book 030, Number 5837: Abu Huraira reported This Hadith has been narrated on the authority of Zuhri with the same chain of transmitters (and the words are):" The newborn child is touched by the Satan (when he comes in the world) and he starts crying because of the touch of Satan."

Sahih Bukhari Volume 1, Book 4, Number 156: Narrated Abu Qatada:

Sahih Bukhari Volume 1, Book 12, Number 717: Narrated Anas bin Malik:

Sahih Al-Bukhari Hadith - 4.447
Narrated Aisha I stuffed for the Prophet a pillow decorated with pictures (of animals) which looked like a Namruqa (i.e. a small cushion). He came and stood among the people with excitement apparent on his face. I said, "O Allah's Apostle! What is wrong?" He said, "What is this pillow?" I said, "I have prepared this pillow for you, so that you may recline on it." He said, "Don't you know that angels do not enter a house wherein there are pictures; and whoever makes a picture will be punished on the Day of Resurrection and will be asked to give life to (what he has created)?"

Satan passes gas in terror when Muslims pray -- Volume 4, Book 54, Number 505:
Narrated Abu Huraira: 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 Rakat: so if one forgets whether he has prayed three or four Rak'a-t, he should perform two prostrations of Sahu (i.e. forgetfulness)."

Satan sleeps in your nose overnight -- Volume 4, Book 54, Number 516:
