It was narrated that Mus'ab bin Sa'd said: "I bowed and put my hands together, and my father said: 'This is something that we used to do, then we brought them up to our knees'."
The act of prayer is a sacred ritual for Muslims, so it is important for believers to observe proper posture and etiquette while engaging in this activity. Not only does this demonstrate respect for God but it also helps believers focus on their prayers more deeply without being distracted by external factors or improper postures. Additionally, teaching children how to properly pray from an early age can help instill a sense of reverence for God within them at an early age which will stay with them throughout their lives.
