﴿ وَإِذْ وَٰعَدْنَا مُوسَىٰٓ أَرْبَعِينَ لَيْلَةًۭ ثُمَّ ٱتَّخَذْتُمُ ٱلْعِجْلَ مِنۢ بَعْدِهِۦ وَأَنتُمْ ظَٰلِمُونَ ﴾

“and when We appointed for Moses forty nights [on Mount Sinai], and in his absence you took to worshipping the [golden] calf, and thus became evildoers:”

(And when We appointed for Moses forty nights) by giving him the scripture, (and then you chose the calf), you worshipped the calf, (when he had gone from you) to the mountain, (and you were wrong-doers) harmful both to yourselves and others.
