It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he (peace and blessings be upon him) said: "When Satan hears the adhan for prayer, he runs away breaking wind, so that he does not hear its sound. When the muezzin falls silent, he comes back and whispers. When he hears the iqamah, he goes away again so that he does not hear its sound, and when he falls silent, he comes back and whispers."
