Put your hands down while prostrating

This hadith teaches us about the etiquette of prostration in prayer. It is narrated from Ibn 'Umar that when one prostrates, they should also put their hands down and when they raise their face, they should also raise their hands. This shows us that we must be mindful of our actions during prayer and follow the etiquette prescribed by Allah's Messenger ﷺ. We must remember to keep our focus on Allah during prayer and not let any distractions take away from it. Additionally, this hadith teaches us to be mindful of our actions in general as we are always being watched by Allah even if no one else is around.
