وَاِذْ وٰعَدْنَا مُوْسٰىٓ اَرْبَعِيْنَ لَيْلَةً ثُمَّ اتَّخَذْتُمُ الْعِجْلَ مِنْۢ بَعْدِهٖ وَاَنْتُمْ ظٰلِمُوْنَ ( البقرة: ٥١ )
Wa iz waa'adnaa Moosaaa arba'eena lailatan summattakhaztumul 'ijla mim ba'dihee wa antum zaalimoon (al-Baq̈arah 2:51)
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. (Al-Baqarah  : 51)
1 Mufti Taqi Usmani
And when We appointed forty nights for Mūsā, then you took the calf (as God) thereafter, and you were unjust.
