114:4An-Naas

"The Messenger of Allah (ﷺ) said: 'When the call to prayer is given, the Shaitan runs away breaking wind loudly. When the Tathwb (Iqamah) is completed, he comes back and whispers to a man in his hear, until he does not know how many (rak'ahs) he has prayed. If any one of you notices that, let him prostrate twice.'"

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."

The Messenger of Allah (ﷺ) said: When the Mu'adhdhin calls to prayer, Satan runs back vehemently.

"When the call for the prayer is given, the Shaitan takes to his heels, passing wind loudly so that he will not hear the call to prayer. When the call to prayer is finished, he comes back. And when the Iqamah is said, he again takes to his heels, and after it is completed, he returns again to interfere between the (praying) person and his heart, saying to him: 'Remember such and such, remember such and such,' - things that he had not remembered - until he does not know how many (Rak'ahs) he has prayed."

The Messenger of Allah (ﷺ) said: The devil takes to his heels breaking wind when the prayer begins. and the rest is the same but with this addition:" He (the devil) makes him think of pleasant things (or things productive of enjoyment) and of the things wished for, and reminds him of such needs which he had forgotten."
