Hadith on replying to the Azaan?

Remaining silent and paying attention to the Azaan has been advised in the Hadith. Rasulullah (Sallallahu Alaihi Wasallam) has said: “When you hear the Azaan, repeat what the Mu’azzin says” (Sahih Muslim).

Based on this Hadith, the Ulama advise that a person should refrain from all conversation and activities during the Azaan. Attention should be paid to the Azaan and the words of the Mu’azzin should be repeated by the listener.

Upon hearing the Mu’azzin saying Hayya Alas Salah and Hayya Alal Falaah, the listener should say ”La Hawla wa La Quwwata illa Billah” as indicated in the Hadith recorded in Sahih Muslim.

It is more rewarding for a person to pause his religious activities and reply to the Azaan even if he is engaged in the recitation of the Qur’an.

With regards to the narration in question: “The holy Prophet Mohammad (SalallaAllahu Alehi Wasallam) said, stop doing everything during the Azan even reading the Quran, (and repeat the Azaan with the Moazzin.) The person who talks during the Azaan will not be able to say the Kalma-e-shahadat on his/her death bed”, we have not found an authentic source for this.

And Allah Knows Best
