"Indeed Allah [Most High] said: 'When I take My slave's sight in the world, then there shall be no reward for him with Me except Paradise.'"  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ يَقُولُ إِذَا أَخَذْتُ كَرِيمَتَىْ عَبْدِي فِي الدُّنْيَا لَمْ يَكُنْ لَهُ جَزَاءٌ عِنْدِي إِلاَّ الْجَنَّةَ وَفِي الْبَابِ عَنْ أَبِي هُرَيْرَةَ وَزَيْدِ بْنِ أَرْقَمَ  

attributed to the Prophet ﷺ that he said that: Allah ﷻ said: "From whomever I took away his two beloved things (his two eye), and he showed patience hoping for reward, I shall not be satisfied with any reward for him less than Paradise."  

رَفَعَهُ إِلَى النَّبِيِّ ﷺ قَالَ يَقُولُ اللَّهُ ﷻ مَنْ أَذْهَبْتُ حَبِيبَتَيْهِ فَصَبَرَ وَاحْتَسَبَ لَمْ أَرْضَ لَهُ ثَوَابًا دُونَ الْجَنَّةِ
