As for the whisper of Satan, it is one of evil and denial of the truth. As for the whisper of the angel, it is one of good and affirmation of the truth. So whoever finds this should know that it is from Allah, so he should praise Allah. And whoever finds the other, let him seek refuge with Allah from Satan, the accursed."

Then, turn to your left three times and seek refuge with Allah from the accursed Satan."
