Legitimate Excuses for staying away from Jihad

Allah mentions here the valid excuses that permit one to stay away from fighting. He first mentions the excuses that remain with a person, the weakness in the body that disallows one from Jihad, such as blindness, limping, and so forth. He then mentions the excuses that are not permanent, such as an illness that would prevent one from fighting in the cause of Allah, or poverty that prevents preparing for Jihad. There is no sin in these cases if they remain behind, providing that when they remain behind, they do not spread malice or try to discourage Muslims from fighting, but all the while observing good behavior in this state, just as Allah said,

مَا عَلَى الْمُحْسِنِينَ مِن سَبِيلٍ وَاللَّهُ غَفُورٌ رَّحِيمٌ

Commentary

Previous verses mentioned people who were not really excusable from participation in Jihad but sat it out because of laziness. Then, there were hypocrites who had taken permission from the Holy Prophet ﷺ under false pretexts because of their disbelief and hypocrisy. And then there were the arrogant ones who did not bother about excuses and permissions and just sat back. They were told there that they were not excusable and that there was a painful punishment waiting for those of them who practiced disbelief and hypocrisy.
