Al Fath Ayah 17

لَّيْسَ عَلَى ٱلْأَعْمَىٰ حَرَجٌ وَلَا عَلَى ٱلْأَعْرَجِ حَرَجٌ وَلَا عَلَى ٱلْمَرِيضِ حَرَجٌ‌ۗ وَمَن يُطِعِ ٱللَّهَ وَرَسُولَهُۥ يُدْخِلْهُ جَنَّـٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَـٰرُ‌ۖ وَمَن يَتَوَلَّ يُعَذِّبْهُ عَذَابًا أَلِيمًا ١٧ There is no blame on the blind, or the disabled, or the sick ?for staying behind?. And whoever obeys Allah and His Messenger will be admitted by Him into Gardens under which rivers flow. But whoever turns away will be subjected by Him to a painful punishment.
