Surah Al-Baqarah (The Cow), Verse 93

وَاِذْ اَخَذْنَا مِیْثَاقَكُمْ وَرَفَعْنَا فَوْقَكُمُ الطُّوْرَ خُذُوْا مَاۤ اٰتَیْنٰكُمْ بِقُوَّةٍ وَّاسْمَعُوْا قَالُوْا سَمِعْنَا وَعَصَیْنَا وَاُشْرِبُوْا فِیْ قُلُوْبِهِمُ الْعِجْلَ بِكُفْرِهِمْ قُلْ بِئْسَمَا یَاْمُرُكُمْ بِهٖۤ اِیْمَانُكُمْ اِنْ كُنْتُمْ مُّؤْمِنِیْنَ ۟

Wa iz akhaznaa meesaaqakum wa rafa'naa fawqa kumut Toora khuzoo maaa aatainaakum biquwwatinw wasma'oo qaaloo sami'naa wa 'asainaa wa ushriboo fee quloobihimul 'ijla bikufrihim; qul bi'samaa yaamurukum biheee eemaanukum in kuntum mu'mineen

“And remember We took your covenant and We raised above you (the towering height) of Mount (Sinai): (Saying): "Hold firmly to what We have given you, and hearken (to the Law)": They said:" We hear, and we disobey:" And they had to drink into their hearts (of the taint) of the calf because of their Faithlessness. Say: "Vile indeed are the behests of your Faith if ye have any faith!"”
