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

Ultimately, there were some of them still left out for the simple reason that they could not find a mount. Rendered totally helpless, they could do nothing about their aspirations for Jihad. These are the kinds of people mentioned in the cited verses whose excuse was accepted by Allah Ta` ala. However, at the end, the warning was repeated by saying that particularly cursed are those who, despite their ability, elected to stay away from Jihad like women. The sentence: الَّذِينَ يَسْتَأْذِنُونَكَ وَهُمْ أَغْنِيَاءُ (Blame lies, in fact, on those who ask your permis-sion despite being rich - 93) means exactly this.
