Place one's hand on the ground before their knee while prostrating in prayer.

This hadith is about the etiquette of prostrating in prayer. The Prophet Muhammad ﷺ taught that when one is in the position of prostration, they should place their hands on the ground before their knees and not kneel like a camel. This teaches us to be mindful of our posture during prayer and to take care to perform it correctly. It also reminds us that we should strive for excellence in all aspects of our lives, even something as small as how we pray. Additionally, this hadith encourages us to be humble and respectful when engaging with Allah SWT by taking care with our posture during prayer.
