Quran 47:17 · Muhammad

It is characteristic of a hypocrite when he is in a serious-minded gathering, to seem to be outwardly very serious while his mind is busy with other things. He does not pay any attention to the words spoken by the preacher. When he comes out of the gathering, he asks other knowledgeable persons, ‘What did the venerable gentleman say?’ This is the price they have to pay on account of their desire-worship. They mire themselves in desire-worship and then are overwhelmed by it. Instead of allowing reason to prevail, they follow their own desires. The result is that their sensitivities become blunted and their minds do not remain capable of grasping the finer shades of reality. Unlike them, those who give importance to reality, and who bow down before true arguments, activate their intellect in the process. The inner knowledge and intense realisation of such individuals increase day-by-day. Their faith is never vitiated by their falling into a state of inertia.
