Al-Fath - 48:17

لَيْسَ عَلَى الْأَعْمَى حَرَجٌ وَلَا عَلَى الْأَعْرَجِ حَرَجٌ وَلَا عَلَى الْمَرِيضِ حَرَجٌ وَمَن يُطِعِ اللَّهَ وَرَسُولَهُ يُدْخِلْهُ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ وَمَن يَتَوَلَّ يُعَذِّبْهُ عَذَابًا أَلِيمًا
[48:17]
There is no harm in the blind, nor is there any harm in the lame, nor is there any harm in the sick (if they do not go forth); and whoever obeys Allah and His Messenger, He will cause him to enter gardens beneath which rivers flow, and whoever turns back, He will punish him with a painful punishment.
No blame is there on the blind, nor is there blame on the lame, nor on one ill (if he joins not the war): But he that obeys Allah and his Messenger,- (Allah) will admit him to Gardens beneath which rivers flow; and he who turns back, (Allah) will punish him with a grievous Penalty.
There is no blame for the blind, nor is there blame for the lame, nor is there blame for the sick (that they go not forth to war). And whoso obeyeth Allah and His messenger, He will make him enter Gardens underneath which rivers flow; and whoso turneth back, him will He punish with a painful doom.
