And remember We appointed forty nights for Moses, and in his absence ye took the calf (for worship), and ye did grievous wrong. (2:51)

And remember Moses said to his people: "O my people! Ye have indeed wronged yourselves by your worship of the calf: So turn (in repentance) to your Maker, and slay yourselves (the wrong-doers); that will be better for you in the sight of your Maker." Then He turned towards you (in forgiveness): For He is Oft-Returning, Most Merciful. (2:54)

The people of the Book ask thee to cause a book to descend to them from heaven: Indeed they asked Moses for an even greater (miracle), for they said: "Show us God in public," but they were dazed for their presumption, with thunder and lightning. Yet they worshipped the calf even after clear signs had come to them; even so we forgave them; and gave Moses manifest proofs of authority. (4:153)

The people of Moses made, in his absence, out of their ornaments, the image of calf, (for worship): it seemed to low: did they not see that it could neither speak to them, nor show them the way? They took it for worship and they did wrong. (7:148)

Those who took the calf (for worship) will indeed be overwhelmed with wrath from their Lord, and with shame in this life: thus do We recompense those who invent (falsehoods). (7:152)

"Then he brought out (of the fire) before the (people) the image of a calf: It seemed to low: so they said: This is your god, and the god of Moses, but (Moses) has forgotten!" (20:88)
