Sura al-Fatḥ 48:17

لَّيْسَ عَلَى ٱلْأَعْمَىٰ حَرَجٌ وَلَا عَلَى ٱلْأَعْرَجِ حَرَجٌ وَلَا عَلَى ٱلْمَرِيضِ حَرَجٌ وَمَن يُطِعِ ٱللَّـهَ وَرَسُولَهُۥ يُدْخِلْهُ جَنَّٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ وَمَن يَتَوَلَّ يُعَذِّبْهُ عَذَابًا أَلِيمًا

laysa ʿalā l-aʿmā ḥarajun wa-lā ʿalā l-aʿraji ḥarajun wa-lā ʿalā l-marīḍi ḥarajun wa-man yuṭiʿi allāha wa-rasūlahu yudkhilhu jannātin tajrī min taḥtihā l-anhāru wa-man yatawalla yuʿadhdhibhu ʿadhāban alīman

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.
