Say "La hawla wa la quwwata illa billahi" whenever you hear a call for prayer or any other time in your life .

This hadith was narrated by Alqamah bin Waqqas, who was present with Mu'awiyah when the Mu'adhdhin called for prayer. Mu'awiyah repeated what the Mu'adhdhin said, but when he said 'Hayya 'alas-salah', he added 'La hawla wa la quwwata illa Billah'. He also added this phrase when the Mu'adhdhin said 'Hayya 'alal-falah'. After that, he repeated what the Mu'adhdhin said. He then mentioned that he heard Prophet Muhammad say exactly like that. This hadith emphasizes on how important it is to say ‘La hawla wa la quwwata illa Billah’ whenever we hear a call for prayer or any other time in our lives. It reminds us that only Allah has power and strength over all things and we should always seek His help in everything we do.
