Pray as long as one feels fresh .

This hadith is about the importance of prayer in Islam. The Prophet Muhammad (PBUH) taught that one should pray as long as they feel fresh and energetic, but when their energy starts to slacken or become tired, then it is time to stop praying and sit down. This teaches us that we must be mindful of our physical limits while praying so we can give our best effort in worshiping Allah. It also shows us the importance of being patient with ourselves; if we are feeling too tired to continue praying then it is okay to take a break instead of pushing ourselves beyond our limits.
