Recite this statement when you hear the Mu'adhdin in order to seek forgiveness from Allah.

This hadith, narrated by Sa'd bin Abi Waqqas, explains that if one recites a specific statement when they hear the Mu'adhdhin, their sins will be forgiven. The statement is "Ashhadu an la ilaha illallah wahdahu la sharika lahu wa anna Muhammadan 'abduhu wa Rasuluhu, raditu Billahi Rabban, wa bil-Islami dinan was bi Muhammadin Rasula" which translates to "I bear witness that there is none worthy of worship except Allah alone, with no partner or associate and that Muhammad is His slave and Messenger; I am content with Allah as my Lord, Islam as my religion and Muhammad as my Messenger". This hadith teaches us about the power of faith and repentance. It encourages us to recite this statement whenever we hear the Mu'adhdhin in order to seek forgiveness from Allah for our sins.
