Affirm your faith in both Allah and his messenger; Repeat after others who recite religious verses or teachings; Respect religion; Learn from others.

This hadith highlights the importance of affirming one's faith in Allah and His Messenger, Muhammad. It was narrated that 'Abdur-Rahman bin Abi Laila said that when 'Ali bin Abi Talib heard the mu'addhin giving the adhan, he used to repeat after him. When he said "I bear witness that there is no god but Allah and I bear witness that Muhammad is the Messenger of Allah", 'Ali would say it too. The hadith emphasizes how important it is to affirm one's faith in both Allah and His messenger, as those who deny this are considered liars. It also shows us how we should follow suit with what we hear from others who are reciting religious verses or teachings. We should take their lead by repeating after them so we can learn more about our religion.
