Respond quickly when you hear the call for prayer so you can pray on time with others in congregation .

This hadith is about adhan and iqamah, which are two important parts of Islamic prayer. Adhan is a call to prayer that is made five times a day, while iqamah is a similar call that signals that it's time for people to line up for prayer. According to this hadith, during the time of Prophet Muhammad (peace be upon him), adhan was pronounced twice in pairs each, while iqamah was pronounced once in pairs each. When people heard iqamah they would perform ablution and go out for prayer. This shows us how important it was for Muslims at that time to respond quickly when they heard the call for prayer so they could pray on time with others in congregation. It also teaches us about the importance of punctuality when responding to religious obligations such as salat or namaz.
