أَفَلَمۡ يَسِيرُواْ فِي ٱلۡأَرۡضِ فَتَكُونَ لَهُمۡ قُلُوبٞ يَعۡقِلُونَ بِهَآ أَوۡ ءَاذَانٞ يَسۡمَعُونَ بِهَاۖ فَإِنَّهَا لَا تَعۡمَى ٱلۡأَبۡصَٰرُ وَلَٰكِن تَعۡمَى ٱلۡقُلُوبُ ٱلَّتِي فِي ٱلصُّدُورِ
Afalam yaseeroo fil ardi fatakoona lahum quloobuny ya'qiloona bihaaa aw aazaanuny yasm'oona bihaa fa innahaa laa ta'mal absaaru wa laakin ta'mal quloobul latee fissudoor
English Translation
So have they not traveled through the earth and have hearts by which to reason and ears by which to hear? For indeed, it is not eyes that are blinded, but blinded are the hearts which are within the breasts
