Appointing Leaders

۞ وَوَٰعَدْنَا مُوسَىٰ ثَلَٰثِينَ لَيْلَةًۭ وَأَتْمَمْنَٰهَا بِعَشْرٍۢ فَتَمَّ مِيقَٰتُ رَبِّهِۦٓ أَرْبَعِينَ لَيْلَةًۭ ۚ وَقَالَ مُوسَىٰ لِأَخِيهِ هَٰرُونَ ٱخْلُفْنِى فِى قَوْمِى وَأَصْلِحْ وَلَا تَتَّبِعْ سَبِيلَ ٱلْمُفْسِدِينَ

We appointed for Moses thirty nights, and completed (the period) with ten (more): thus was completed the term (of communion) with his Lord, forty nights. And Moses had charged his brother Aaron (before he went up): "Act for me amongst my people: Do right, and follow not the way of those who do mischief."

وَلَمَّا رَجَعَ مُوسَىٰٓ إِلَىٰ قَوْمِهِۦ غَضْبَٰنَ أَسِفًۭا قَالَ بِئْسَمَا خَلَفْتُمُونِى مِنۢ بَعْدِىٓ ۖ أَعَجِلْتُمْ أَمْرَ رَبِّكُمْ ۖ وَأَلْقَى ٱلْأَلْوَاحَ وَأَخَذَ بِرَأْسِ أَخِيهِ يَجُرُّهُۥٓ إِلَيْهِ ۚ قَالَ ٱبْنَ أُمَّ إِنَّ ٱلْقَوْمَ ٱسْتَضْعَفُونِى وَكَادُوا۟ يَقْتُلُونَنِى فَلَا تُشْمِتْ بِىَ ٱلْأَعْدَآءَ وَلَا تَجْعَلْنِى مَعَ ٱلْقَوْمِ ٱلظَّٰلِمِينَ

When Moses came back to his people, angry and grieved, he said: "Evil it is that ye have done in my place in my absence: did ye make haste to bring on the judgment of your Lord?" He put down the tablets, seized his brother by (the hair of) his head, and dragged him to him. Aaron said: "Son of my mother! the people did indeed reckon me as naught, and went near to slaying me! Make not the enemies rejoice over my misfortune, nor count thou me amongst the people of sin."
