Allah(swt), told us to make us realize

 أَفَلَمْ يَسِيرُوا فِي الْأَرْضِ فَتَكُونَ لَهُمْ قُلُوبٌ يَعْقِلُونَ بِهَا أَوْ آذَانٌ يَسْمَعُونَ بِهَا فَإِنَّهَا لَا تَعْمَى الْأَبْصَارُ وَلَكِن تَعْمَى الْقُلُوبُ الَّتِي فِي الصُّدُورِ 22:46

(Fathe Muhammad Jalandari)
کيا ان لوگوں نے ملک ميں سير نہيں کي تاکہ ان کے دل (ايسے) ہوتے کہ ان سے سمجھ سکتے. اور کان (ايسے) ہوتے کہ ان سے سن سکتے. بات يہ ہے کہ آنکھيں اندھي نہيں ہوتيں بلکہ دل جو سينوں ميں ہيں (وہ) اندھے ہوتے ہيں22:46

(Muhammad Assad)
 22:46 Have they, then, never journeyed about the earth, letting their hearts gain wisdom, and causing their ears to hear? Yet, verily, it is not their eyes that have become blind - but blind have become the hearts that are in their breasts!22:46

(Yousaf Ali)
 22:46 Do they not travel through the land, so that their hearts (and minds) may thus learn wisdom and their ears may thus learn to hear? Truly it is not their eyes that are blind, but their hearts which are in their breasts.22:46
