Al-Baqarah · Ayah 51
وَإِذْ وَٰعَدْنَا مُوسَىٰٓ أَرْبَعِينَ لَيْلَةً ثُمَّ ٱتَّخَذْتُمُ ٱلْعِجْلَ مِنۢ بَعْدِهِۦ وَأَنتُمْ ظَٰلِمُونَ
And [recall] when We made an appointment with Moses for forty nights. Then you took [for worship] the calf after him [i.e., his departure], while you were wrongdoers.
