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.

And Allah turned back the unbelievers in their rage; they did not obtain any advantage, and Allah sufficed the believers in fighting; and Allah is Strong, Mighty.

That was because there came to them their messengers with clear arguments, but they rejected (them), therefore Allah destroyed them; surely He is Strong, Severe in retribution.
