وَجَعَلْنَا عَلَى قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِي آذَانِهِمْ وَقْرًا وَإِذَا ذَكَرْتَ رَبَّكَ فِي الْقُرْآنِ وَحْدَهُ وَلَّوْاْ عَلَى أَدْبَارِهِمْ نُفُورًا
﴿٤٦﴾
سورة الإسراء
(17/46) And We have placed Ekinnet (coverings) on their hearts and a Vakra (heaviness) in their ears to prevent them from comprehending it (the Qur’ân). And when you mention your Lord Alone in the Qur’ân, they turned their backs in aversion.
Surah Al-Isra
