And We have put coverings over their hearts lest they should understand it (the Qur’ân), and in their ears deafness. And when you make mention of your Lord Alone [Lâ ilâha illallâh (none has the right to be worshipped but Allâh) Islâmic Monotheism (توحيد الله)] in the Qur’ân, they turn on their backs, fleeing in extreme dislike.
