Pray with vigor and enthusiasm ; Take care of one's health while performing religious duties ; Understand when it is better to rest than push oneself too hard

This hadith highlights the importance of prayer in Islam. It teaches us that we should pray with vigor and enthusiasm, and not rely on external aids such as a rope to keep us standing for prayer. The Prophet Muhammad ﷺ was concerned about Zainab's wellbeing, but he wanted her to understand that she should only pray when she feels active and energetic. When she gets tired, it is better for her to sit down instead of relying on an external aid like a rope. This hadith also teaches us that we should take care of our health while performing religious duties; if we are too tired or ill, then it is better for us to rest instead of pushing ourselves too hard.
