Practice moderation when performing small actions such as smoothing pebbles during prayer.

The Prophet Muhammad (peace be upon him) taught us to practice moderation in our prayers. He advised that if we must smooth the pebbles during prayer, then we should only do it once. This hadith teaches us that even when performing small actions such as smoothing pebbles, we should still practice moderation and not overdo it. We can apply this lesson to other aspects of our lives as well; for example, when studying for an exam or completing a project at work, it is important to take breaks and not overwork ourselves. This hadith reminds us of the importance of balance and moderation in all aspects of life.
