Quran 2:92 — The Heifer (Al-Baqarah)

Moses went to you with profound miracles, yet you worshiped the calf in his absence, and you turned wicked.

[2:91] When they are told, "You shall believe in these revelations of GOD," they say, "We believe only in what was sent down to us." Thus, they disbelieve in subsequent revelations, even if it is the truth from their Lord, and even though it confirms what they have! Say, "Why then did you kill GOD's prophets, if you were believers?"

[2:93] We made a covenant with you, as we raised Mount Sinai above you, saying, "You shall uphold the commandments we have given you, strongly, and listen." They said, "We hear, but we disobey." Their hearts became filled with adoration for the calf, due to their disbelief. Say, "Miserable indeed is what your faith dictates upon you, if you do have any faith."
