What! he who is obedient during hours of the night, prostrating himself and standing, takes care of the hereafter and hopes for the mercy of his Lord! Say: Are those who know and those who do not know alike? Only the men of understanding are mindful.

And when you see them, their persons will please you, and If they speak, you will listen to their speech; (they are) as if they were big pieces of wood clad with garments; they think every cry to be against them. They are the enemy, therefore beware of them; may Allah destroy them, whence are they turned back?
