Allah's Messenger (ﷺ) said, "When the Adhan is pronounced Satan takes to his heels and passes wind with noise during his flight in order not to hear the Adhan. When the Adhan is completed he comes back and again takes to his heels when the Iqama is pronounced and after its completion he returns again till he whispers into the heart of the person (to divert his attention from his prayer) and makes him remember things which he does not recall to his mind before the prayer and that causes him to forget how much he has prayed."

Allah's Messenger (ﷺ) said, "When the Adhan for the prayer is pronounced, then Satan takes to his heels passing wind so that he may not hear the Adhan and when the Mu'adh-dhin finishes, he comes back; and when the Iqama is pronounced he again takes to his heels and when it is finished, he again comes back and continues reminding the praying person of things that he used not to remember when not in prayer till he forgets how much he has prayed." Abu Salama bin `Abdur-Rahman said, "If anyone of you has such a thing (forgetting the number of rak`at he has prayed) he should perform two prostrations of Sahu (i.e. forgetfulness) while sitting." Abu Salama narrates this from Abu Huraira.

Do not sit with those who believe in free will and do not address them before they address you.

When one of you sees a vision which he dislikes, he must spit on his left (three times), seek refuge in Allah from the devil three times, and turn from the side on which he was lying.

The Apostle (ﷺ) said When the call to prayer is made, Satan runs back and breaks wind so as not to hear the call being made, and when the call is finished. he turns round. When Iqama is proclaimed he turns his back, and when it is finished he turns round to distract a man, saying: Re- member such and such; remember such and such, referring to something the man did not have in his mind, with the result that he does not know how much he has prayed.
