It was narrated that Sa’ib bin Yazid said: "The Messenger of Allah ﷺ had only one Mu’adh-dhin. When he came out he would give the Adhan and when he came down (from the pulpit) he would give the Iqamah. Abu Bakr and 'Umar did likewise, but when 'Uthman (became caliph) the numbers of people had increased, he added the third call from atop a house in the marketplace that was called Zawra’. When he came out (the Mu’adh-dhin) would call the Adhan, and when he came down from the pulpit, he would call the Iqamah.
The importance of prayer is highlighted by this hadith as it shows us that even though there were more people during 'Uthman's time as caliph he still made sure to add another call so that everyone could hear it clearly and respond accordingly. This teaches us that we should always strive to make our prayers meaningful by responding promptly whenever we hear them being called out loud or even if we just remember them ourselves without anyone else reminding us about it.
