وَعَن أَنَسٍ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: قَالَ اللَّهُ سُبْحَانَهُ وَتَعَالَى: إِذَا ابْتَلَيْتُ عَبْدِي بِحَبِيبَتَيْهِ ثُمَّ صَبَرَ عَوَّضْتُهُ مِنْهُمَا الْجنَّة يُرِيد عَيْنَيْهِ. رَوَاهُ البُخَارِيّ
Anas said he heard the Prophet (ﷺ) declare that God who is glorious and exalted said, “When I afflict my servant in his two loved things (i.e. his eyes), and he endures patiently, I shall compensate him for them with paradise.” Bukhari transmitted it.
