الحج — Al-Hajj Ayat 46
اَفَلَمْ يَسِيْرُوْا فِى الْاَرْضِ فَتَكُوْنَ لَهُمْ قُلُوْبٌ يَّعْقِلُوْنَ بِهَآ اَوْ اٰذَانٌ يَّسْمَعُوْنَ بِهَاۚ فَاِنَّهَا لَا تَعْمَى الْاَبْصَارُ وَلٰكِنْ تَعْمَى الْقُلُوْبُ الَّتِيْ فِى الصُّدُوْرِ
Afalam yasīrū fil-arḍi fa takūna lahum qulūbuy ya‘qilūna bihā au āżānuy yasma‘ūna bihā, fa innahā lā ta‘mal-abṣāru wa lākin ta‘mal-qulūbul-latī fiṣ-ṣudūr(i).
"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."
