خَلَفَ

وَلَوْ نَشَآءُ لَجَعَلْنَا مِنكُم مَّلَـٰٓئِكَةًۭ فِى ٱلْأَرْضِ يَخْلُفُونَ

And if We willed, We could have made [instead] of you angels succeeding [one another] on the earth.

۞ فَخَلَفَ مِنۢ بَعْدِهِمْ خَلْفٌ أَضَاعُوا۟ ٱلصَّلَوٰةَ وَٱتَّبَعُوا۟ ٱلشَّهَوَٰتِ ۖ فَسَوْفَ يَلْقَوْنَ غَيًّا

But there came after them successors [i.e., later generations] who neglected prayer and pursued desires; so they are going to meet evil -

۞ وَوَٰعَدْنَا مُوسَىٰ ثَلَـٰثِينَ لَيْلَةًۭ وَأَتْمَمْنَـٰهَا بِعَشْرٍۢ فَتَمَّ مِيقَـٰتُ رَبِّهِۦٓ أَرْبَعِينَ لَيْلَةًۭ ۚ وَقَالَ مُوسَىٰ لِأَخِيهِ هَـٰرُونَ ٱخْلُفْنِى فِى قَوْمِى وَأَصْلِحْ وَلَا تَتَّبِعْ سَبِيلَ ٱلْمُفْسِدِينَ

And We made an appointment with Moses for thirty nights and perfected them by [the addition of] ten; so the term of his Lord was completed as forty nights. And Moses said to his brother Aaron, "Take my place among my people, do right [by them], and do not follow the way of the corrupters."
