Surah Al-Fat'h (The Victory), Verse 17

لَیْسَ عَلَی الْاَعْمٰی حَرَجٌ وَّلَا عَلَی الْاَعْرَجِ حَرَجٌ وَّلَا عَلَی الْمَرِیْضِ حَرَجٌ وَمَنْ یُّطِعِ اللّٰهَ وَرَسُوْلَهٗ یُدْخِلْهُ جَنّٰتٍ تَجْرِیْ مِنْ تَحْتِهَا الْاَنْهٰرُ وَمَنْ یَّتَوَلَّ یُعَذِّبْهُ عَذَابًا اَلِیْمًا 

Laisa 'alal a'maa harajunw wa laa 'alal a'raji harajunw wa laa 'alal mareedi haraj' wa many yutil'il laaha wa Rasoolahoo yudkhilhu jannaatin tajree min tahtihal anhaaru wa many yatawalla yu'azzibhu 'azaaban aleemaa

“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.”
