This hadith is about the Prophet Muhammad's practice of offering prayers in different locations. He offered a four-rak'at Zuhr prayer at Medina and then offered a two rak'at 'Asr prayer at Dhul-Hulaifa. Additionally, the companions of the Prophet recited Talbiya aloud for Hajj and Umra. This hadith teaches us that it is important to be mindful of our prayers no matter where we are or what we are doing. It also shows us that it is important to be vocal about our faith by reciting religious phrases such as talbiyyah out loud when performing religious activities like hajj or umrah.
