And who does greater wrong than he who has been reminded of the revelations of his Lord, yet turns away from them and forgets what his hands have sent forth. Indeed, We have placed coverings over their hearts lest they should understand this (Quran), and in their ears a deafness. And if you call them to guidance, they will never be guided, then ever. [Qur’an 2:57]
