Be respectful towards others while praying by not spitting in front or on your right side but rather on your left side under your left foot.

The Prophet Muhammad ﷺ taught us that when we are in prayer, we are speaking privately with our Lord and should therefore be mindful of our etiquette. We should not spit in front of us or to the right side while praying, but instead should direct it towards the left side under our left foot. This teaches us that even during prayer we must maintain proper etiquette and respect for those around us. It also reminds us that although prayer is a private conversation between ourselves and Allah, it is still important to be mindful of how we conduct ourselves as Muslims even when no one else is watching.
