(186) Chapter: The Excellence of Adhan

Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, "When you hear the Mu'adhdhin (pronouncing the call to Salat), repeat after him what he says."

[Al-Bukhari and Muslim].

Commentary: This Hadith also tells us to repeat the words of Adhan when we hear it. But when he says "Hayya`alas-Salah'' or "Hayya `alal-Falah'' we must say "La hawla wa la quwwata illa billah.''
