Replying to the azaan:

The azaan is among the salient symbols of Islam. When azaan holds such great importance in Deen, then we should show respect and appreciation to Allah Ta‘ala by replying to the azaan and not being engaged in any worldly talk at that time. The Fuqahaa have written that it is makrooh to engage in worldly talk at the time of azaan.

1. When one hears the azaan, one should reply to the azaan by repeating the words that the muazzin has called out.

For example, when one hears the muazzin saying, “الله أكبر الله أكبر (Allaahu Akbar Allaahu Akbar)”, he should reply by also saying, “الله أكبر الله أكبر (Allaahu Akbar Allaahu Akbar)”.
