Praying While Feeling Active
Anas (radi Allahu anhu) reported that the Prophet (sal Allahu alaihi wa sallam) came into the mosque and noticed a rope stretched between two poles. He enquired, “What is this rope for?” He was told: “This is Zainab’s rope. When during her voluntary prayer, she begins to feel tired, she grasps it for support.” The Prophet (sal Allahu alaihi wa sallam) said, “Untie it. You should perform prayers so long as you feel active. When you feel tired, you should go to sleep.”
[Sahih Al-Bukhari and Muslim]
This Hadith deals with the following three points:
1. It forbids undue strictness and taking support of anything in the course of Salat.
2. If wrong can be corrected by hand, it must be stopped immediately.
3. One should be moderate in worship and select such times for optional and voluntary prayers when one feels real pleasure in them.
And Allah Knows Best!
