Volume 1, Book 11, Number 582:
Narrated Abu Huraira:
Allah’s Apostle 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 for –
get how much he has prayed.”
