وَوٰعَدْنَا مُوْسٰي ثَلٰثِيْنَ لَيْلَةً وَّاَتْمَمْنٰهَا بِعَشْرٍ فَتَمَّ مِيْقَاتُ رَبِّهٖٓ اَرْبَعِيْنَ لَيْلَةًۚ وَقَالَ مُوْسٰي لِاَخِيْهِ هٰرُوْنَ اخْلُفْنِيْ فِيْ قَوْمِيْ وَاَصْلِحْ وَلَا تَتَّبِعْ سَبِيْلَ الْمُفْسِدِيْنَ ١٤٢
Translation
We made an appointment with Moses for thirty nights, and completed them with ten [more]; thus the tryst of his Lord was completed in forty nights. And Moses said to Aaron, his brother, ‘Be my successor among my people, and set things right and do not follow the way of the agents of corruption.’
