Be consistent when calling people to prayer; Be mindful when performing religious duties; Follow Prophet Muhammad's example

This hadith is about how Prophet Muhammad's companion, Bilal, used to call people to prayer with two phrases repeated twice in his adhan and once in his iqama. This shows us that Muslims should be consistent when they are calling people to prayer. It also teaches us that we should be mindful when we are performing religious duties like salat or namaz as it is a form of worshiping Allah. Furthermore, this hadith also reminds us that we should follow Prophet Muhammad's example as he was an exemplary role model for all Muslims.
