Quran 2:51 — Surah Al-Baqarah, ayah 51

وَإِذۡ وَٰعَدۡنَا مُوسَىٰٓ أَرۡبَعِينَ لَيۡلَةٗ ثُمَّ ٱتَّخَذۡتُمُ ٱلۡعِجۡلَ مِنۢ بَعۡدِهِۦ وَأَنتُمۡ ظَٰلِمُونَ

And [recall] when We made an appointment with Moses for forty nights. Then you took [for worship] the calf after him, while you were wrongdoers

i kada smo Musau četrdeset noći obećanje ispunjavali, vi ste, u njegovu odsustvu, sami sebi čineći nepravdu, tele obožavati počeli.
