Al-An'am · 6:25

25. Some of the idolaters listen to you, O Messenger, when you recite the Qur’ān, but they do not benefit from what they hear because I have placed covers on their hearts so that they cannot understand the Qur’ān. I did this due to their stubbornness and their turning away. I have made their ears deaf to beneficial listening. Despite the clear indications and glaring evidences that they see, they still do not believe, such that when they come to you they present false arguments against the truth and say: What you have brought has simply been taken from the books of the earlier people.
