Waja'alnā 'alā qulūbihim akinnatan an yafqahūhu wafī ādhānihim waqran wa idhā dhakarta rabbaka fil-qur'āni wahdahū wallaw 'alā adbārihim nufūrā
And We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And when you mention your Lord alone in the Qur’ān, they turn back in aversion.
