(And when We did appoint for Moses) to spend in the mountain (thirty nights (of solitude)) the month of the Dhu'l-Qa'dah, (and added to them ten) days from the month of Dhu'l-Hijjah, (and he completed the whole time appointed by his Lord of forty nights) as he promised; (and Moses said unto his brother: Take my place) be my deputy (among the people. Do right) enjoin them to do right, (and follow not the way of mischief-makers) by committing transgressions.
- 7:142142
۞ وَوَاعَدْنَا مُوسَىٰ ثَلَاثِينَ لَيْلَةً وَأَتْمَمْنَاهَا بِعَشْرٍ فَتَمَّ مِيقَاتُ رَبِّهِ أَرْبَعِينَ لَيْلَةً ۚ وَقَالَ مُوسَىٰ لِأَخِيهِ هَارُونَ اخْلُفْنِي فِي قَوْمِي وَأَصْلِحْ وَلَا تَتَّبِعْ سَبِيلَ الْمُفْسِدِينَ
We made an appointment of thirty nights with Moses (On Mount Sinai) to which We added ten more; so the term set by the Lord was completed in forty nights. Moses said to Aaron, his brother: "Deputise for me among my people. Dispose rightly, and do not follow the way of the authors of evil."
