۞ وَوَٰعَدْنَا مُوسَىٰ ثَلَـٰثِينَ لَيْلَةًۭ وَأَتْمَمْنَـٰهَا بِعَشْرٍۢ فَتَمَّ مِيقَـٰتُ رَبِّهِۦٓ أَرْبَعِينَ لَيْلَةًۭ ۚ وَقَالَ مُوسَىٰ لِأَخِيهِ هَـٰرُونَ ٱخْلُفْنِى فِى قَوْمِى وَأَصْلِحْ وَلَا تَتَّبِعْ سَبِيلَ ٱلْمُفْسِدِينَ ١٤٢
We appointed for Moses thirty nights then added another ten—completing his Lord’s term of forty nights. Moses commanded his brother Aaron, “Take my place among my people, do what is right, and do not follow the way of the corruptors.”
