And when We made a covenant with you and raised the mountain over you: Take hold of what We have given you with firmness and be obedient. They said: We hear and disobey. And they were made to imbibe (the love of) the calf into their hearts on account of their unbelief Say: Evil is that which your belief bids you if you are believers.

O Messenger! let not those grieve you who strive together in hastening to unbelief from among those who say with their mouths: We believe, and their hearts do not believe, and from among those who are Jews; they are listeners for the sake of a lie, listeners for another people who have not come to you; they alter the words from their places, saying: If you are given this, take it, and if you are not given this, be cautious; and as for him whose temptation Allah desires, you cannot control anything for him with Allah. Those are they for whom Allah does not desire that He should purify their hearts; they shall have disgrace in this world, and they shall have a grievous chastisement in the hereafter.

And of them is he who hearkens to you, and We have cast veils over their hearts lest they understand it and a heaviness into their ears; and even if they see every sign they will not believe in it; so much so that when they come to you they only dispute with you; those who disbelieve say: This is naught but the stories of the ancients.
