Islam

 Isa bin Talhah said: I was with Mu´awiyah bin Abu Sufyan when the Mu´adhdhin came in and called for prayer. Mu´awiyah said: ´´I heard the Messenger of Allah salla alayhi wa sallam say: The Mu´adhdhin will have the longest necks on the Day of Resurrection.´´´

 Narrated that the Prophet salla alayhi wa sallam said: ´´When the Adhan is pronounced, Satan takes to his heels and passes wind to aviod hearing the Adhan. When the Adhan is over, he comes back, and again takes to his heels when the Iqamah is pronounced and after its completion, he returns to whisper into the heart of a person (to distract his attention from his prayer) and makes him remember things which he does not recall before until man forgets how many Ra´kah he prayed.´´

 Anas bin Malik narrated: The Messenger of Allah salla alayhi wa sallam used to attack the enemy at fawn. He would listen to the Adhan; so if he heard it, he stopped otherwise he charged. Once on hearing a man say: ´´Allah is the Greatest, Allah is the Greatest,´´ the Messenger of Allah salla alayhi wa sallam remarked: ´´He is following Al-Fitrah (Islam).´´ Then hearing him say: ´´I testify that there is no true God but Allah, there is no true God but Allah,´´ the Messenger of Allah salla alayhi wa sallam said: ´´You have come out of Fire (of Hell).´´ They looked and found that he was a shepherd.

 ´Aishah narrated that Ibn Umm Maktum used to call Adhan for the Messenger of Allah salla alayhi wa sallam and he was blind.

 Abdullah bin ´Umar narrated that the Messenger of Allah salla alayhi wa sallam had two Mu´adhdhin, Bilal and ´Abdullah bin Umm Maktum, who (latter) became blind.

 Anas narrated: ´´Bilal was ordered to pronounce the woriding of Adhan twice (in doubles) and of Iqamah once (in singles) only.´´ Yahya added in his narration from Ibn ´Uaiyah: ´´I mentioned that to Ayyub and he said, ´Except Iqamah (i.e., Qad Qamatis.salat which should be said twice)´.´´
