#152 Yahya related to me from Malik from Abu'z-Zinad from al-Araj from
Abu Hurayra that the Messenger of Allah, may Allah bless him and grant
him peace, said, "When the call to prayer is made Shaytan retreats,
passing wind, so that he will not hear the adhan. When the adhan is
completed he comes back, until, when the iqama is said, he retreats
again. When the iqama is completed, he comes back, until he comes
between a man and his self and says, 'Think of such and such, think of
such and such,' which he was not thinking about before, until the man
does not know how much he has prayed."
