قُلْ أَرَءَيْتُمْ إِنْ أَخَذَ ٱللَّهُ سَمْعَكُمْ وَأَبْصَٰرَكُمْ وَخَتَمَ عَلَىٰ قُلُوبِكُم مَّنْ إِلَٰهٌ غَيْرُ ٱللَّهِ يَأْتِيكُم بِهِ ۗ ٱنظُرْ كَيْفَ نُصَرِّفُ ٱلْءَايَٰتِ ثُمَّ هُمْ يَصْدِفُونَ
Say: Have ye imagined, if Allah should take away your hearing and your sight and seal your hearts, Who is the Allah Who could restore it to you save Allah? See how We display the revelations unto them! Yet still they turn away.
Surah Al-An'aam(6:46)
