Surat Fuşşilat - سورة فصلت

وَقَالُوا قُلُوبُنَا فِي أَكِنَّةٍ مِّمَّا تَدْعُونَا إِلَيْهِ وَفِي آذَانِنَا وَقْرٌ وَمِن بَيْنِنَا وَبَيْنِكَ حِجَابٌ فَاعْمَلْ إِنَّنَا عَامِلُونَ

Muhsin Khan: And they say: "Our hearts are under coverings (screened) from that to which you invite us, and in our ears is deafness, and between us and you is a screen, so work you (on your way); verily, we are working (on our way)."
