Quran 2:93 Al-Baqarah, ayah 93 of 286

وَإِذْ أَخَذْنَا مِيثَـٰقَكُمْ وَرَفَعْنَا فَوْقَكُمُ ٱلطُّورَ خُذُوا۟ مَآ ءَاتَيْنَـٰكُم بِقُوَّةٍ وَٱسْمَعُوا۟ ۖ قَالُوا۟ سَمِعْنَا وَعَصَيْنَا وَأُشْرِبُوا۟ فِى قُلُوبِهِمُ ٱلْعِجْلَ بِكُفْرِهِمْ ۚ قُلْ بِئْسَمَا يَأْمُرُكُم بِهِۦٓ إِيمَـٰنُكُمْ إِن كُنتُم مُّؤْمِنِينَ ۝٩٣

2:93 And when We made with you a covenant and caused the Mount to tower above you, (saying): Hold fast by that which We have given you, and hear (Our Word), they said: We hear and we rebel. And (worship of) the calf was made to sink into their hearts because of their rejection (of the covenant). Say (unto them): Evil is that which your belief enjoineth on you, if ye are believers.
