Hazrat Qatadah narrates that when Hazrat Usman heard the voice of the muezzin, he would repeat the same words as the muezzin during the tashahhud and takbeer. However, when the muezzin said "Hayya 'ala-s-Salah," he would say "Ma sha' Allah, wa la hawla wa la quwwata illa billah," and when the muezzin said "Qad qamatis salah," he would say: "Welcome to those who speak of justice and truth, and welcome to the prayer," and then he would stand up for the prayer.

Hazrat Abdullah bin Shaqiq says that a sign of hardness of the heart is that you hear the muezzin saying La ilaha illallah, Allahu Akbar, but you do not respond to it.

Yahya Bakkā’ says that during Ṭawāf, I was holding the hand of Ḥaḍrat Ibn ʿUmar (may Allah be pleased with them both). Meanwhile, a muezzin of the Kaʿbah met him and said,“I love you for the sake of Allah.”Ḥaḍrat Ibn ʿUmar (may Allah be pleased with them both) replied,“I hate you for the sake of Allah because you beautify your voice for the sake of obtaining dirhams.”

It is narrated from Hazrat Abu Huraira that the Messenger of Allah, peace and blessings be upon him, said: When the muezzin calls the adhan for prayer, Satan turns away and flees in such a manner that even his wind passes out. When the adhan is completed, he returns, and when the iqamah is pronounced, he flees again. (41) The excellence in the call to prayer.

Hazrat Umar bin Saeed Makki says that a muezzin gave the adhan in a melodious manner, so Hazrat Umar bin Abdul Aziz said to him, "Give the adhan in a simple way, or else go far away from us."
