And the Prophet Muhammad (peace be upon him) said: When the call to prayer (adhan) is given, Satan runs away while passing wind loudly so that he does not hear the adhan. When the adhan is finished, he comes back. Then when the iqamah is pronounced, he runs away again, and when the iqamah is completed, he returns and puts whispers into the heart of a person and says, "Remember such and such thing, remember such and such thing," and he reminds him of things which he did not remember before, to the extent that a person does not even remember how many rak'ahs he has prayed?
