Be mindful while praying, maintain a certain distance from your qiblal so you can focus on your prayers without any distractions, keep your head low while praying .

This hadith is about the prayer of Prophet Muhammad ﷺ and how he prayed with a distance of three cubits between him and the qiblah. The qiblah is a direction that Muslims face when they pray, which points towards Kaaba in Makkah. This hadith teaches us to be mindful while praying, to maintain a certain distance from our qiblah so that we can focus on our prayers without any distractions. It also teaches us to be humble in our prayers as it was narrated that Prophet ﷺ used to keep his head low while praying.
