Quran 22:46 Al-Hajj, ayah 46 of 78

أَفَلَمْ يَسِيرُوا۟ فِى ٱلْأَرْضِ فَتَكُونَ لَهُمْ قُلُوبٌ يَعْقِلُونَ بِهَآ أَوْ ءَاذَانٌ يَسْمَعُونَ بِهَا ۖ فَإِنَّهَا لَا تَعْمَى ٱلْأَبْصَـٰرُ وَلَـٰكِن تَعْمَى ٱلْقُلُوبُ ٱلَّتِى فِى ٱلصُّدُورِ ۝٤٦

22:46 Have they not travelled in the land, and have they hearts wherewith to feel and ears wherewith to hear? For indeed it is not the eyes that grow blind, but it is the hearts, which are within the bosoms, that grow blind.
