Repeat after them when hearing someone calling out for prayer

This hadith is about responding to the call of adhan. The Prophet Muhammad instructed his followers to repeat what is said by the mu’aththin al-deen or caller of prayer when he calls out for adhan. This means that when we hear someone calling out for prayer in a mosque or any other place, we should respond by repeating what they say after them. This shows respect and obedience towards Allah and His Messenger as well as following Islamic teachings and traditions. It also serves as a reminder that Allah is always with us and He hears our prayers no matter where we are or what we are doing. By responding to this call, it helps us stay connected with Him at all times.
