Quran 5:71 from Surah Al-Maaida on Divine Marvels.
وَحَسِبُوٓاْ أَلَّا تَكُونَ فِتۡنَةٞ فَعَمُواْ وَصَمُّواْ ثُمَّ تَابَ ٱللَّهُ عَلَيۡهِمۡ ثُمَّ عَمُواْ وَصَمُّواْ كَثِيرٞ مِّنۡهُمۡۚ وَٱللَّهُ بَصِيرُۢ بِمَا يَعۡمَلُونَ
English translation: And they thought that not will be (for them) a trial so they became blind and they became deaf Then turned Allah to them then (again) they became blind and they became deaf many of them And Allah (is) All-Seer of what they do
Transliteration: wahasibu alla takuna fit'natun fa'amu wasammu thumma taba al-lahu alayhim thumma amu wasammu kathirun min'hum wal-lahu basirun bima ya'maluna
