And among them are some who listen to your discourse on practical divinity and to the Quran when you recite it, not to profit by it but to pick holes in it and be able to tell their evil minds. The fact is that We have closed their hearts’ ears and deafened their ears to reason. They just would not apprehend with their senses any revelation or any sign no matter how convincing to the mind they be. And when they come to you O Muhammad they do not humble themselves but in arrogance they are more ready to argue than to obey. Vested with infidelity, they interpret their thoughts in words: "This is nothing", they say, "but fables of old".
