أَفَلَمْ يَسِيرُوا فِي الْأَرْضِ فَتَكُونَ لَهُمْ قُلُوبٌ يَعْقِلُونَ بِهَا أَوْ آذَانٌ يَسْمَعُونَ بِهَا ۖ فَإِنَّهَا لَا تَعْمَى الْأَبْصَارُ وَلَٰكِن تَعْمَى الْقُلُوبُ الَّتِي فِي الصُّدُورِ (46)
(22:46) Have they not gone about in the land so as to make their hearts think and ears hear? The fact, however, is that it is the hearts in the breasts and not the eyes that become blind. *91
*91) The words ".... the hearts .... blind" have been used in the metaphorical and not in the literal sense. Since the heart is regarded as the centre of emotions, feelings and of mental and moral qualities, these words have been used to imply that their obduracy has inhibited them from feeling and acting rationally.
