Sura al-Aʿrāf 7:142

وَوَٰعَدْنَا مُوسَىٰ ثَلَٰثِينَ لَيْلَةً وَأَتْمَمْنَٰهَا بِعَشْرٍ فَتَمَّ مِيقَٰتُ رَبِّهِۦٓ أَرْبَعِينَ لَيْلَةً وَقَالَ مُوسَىٰ لِأَخِيهِ هَٰرُونَ ٱخْلُفْنِى فِى قَوْمِى وَأَصْلِحْ وَلَا تَتَّبِعْ سَبِيلَ ٱلْمُفْسِدِينَ

wa-wāʿadnā mūsā thalāthīna laylatan wa-atmamnāhā biʿashrin fatamma mīqātu rabbihi arbaʿīna laylatan wa-qāla mūsā liakhīhi hārūna akhlufnī fī qawmī wa-aṣliḥ wa-lā tattabiʿ sabīla l-mufsidīna

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."

Sura al-Aʿrāf 7:150

وَلَمَّا رَجَعَ مُوسَىٰٓ إِلَىٰ قَوْمِهِۦ غَضْبَٰنَ أَسِفًا 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

wa-lammā rajaʿa mūsā ilā qawmihi ghaḍbāna asifan qalā biʾsamā khalaftumūnī min baʿdī aʿajiltum amra rabbikum wa-alqa l-alwāḥa wa-akhadha bi-raʾsi akhīhi yajurruhu ilayhi qalā ibna umma inna l-qawma istaḍʿafūnī wa-kādū yaqtulūnanī fa-lā tushmit biya l-aʿdāʾa wa-lā tajʿalnī maʿa l-qawmi l-ẓālimīna

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."

Sura al-Aʿrāf 7:169

فَخَلَفَ مِنۢ بَعْدِهِمْ خَلْفٌ وَرِثُوا۟ ٱلْكِتَٰبَ يَأْخُذُونَ عَرَضَ هَٰذَا ٱلْأَدْنَىٰ وَيَقُولُونَ سَيُغْفَرُ لَنَا وَإِن يَأْتِهِمْ عَرَضٌ مِّثْلُهُۥ يَأْخُذُوهُ أَلَمْ يُؤْخَذْ عَلَيْهِم مِّيثَٰقُ ٱلْكِتَٰبِ أَن لَّا يَقُولُوا۟ عَلَى ٱللَّـهِ إِلَّا ٱلْحَقَّ وَدَرَسُوا۟ مَا فِيهِ وَٱلدَّارُ ٱلْأَخِرَةُ خَيْرٌ لِّلَّذِينَ يَتَّقُونَ أَفَلَا تَعْقِلُونَ

After them succeeded an (evil) generation: They inherited the Book, but they chose (for themselves) the vanities of this world, saying (for excuse): "(Everything) will be forgiven us." (Even so), if similar vanities came their way, they would (again) seize them. Was not the covenant of the Book taken from them, that they would not ascribe to Allah anything but the truth? and they study what is in the Book. But best for the righteous is the home in the Hereafter. Will ye not understand?

Sura Maryam 19:59

فَخَلَفَ مِنۢ بَعْدِهِمْ خَلْفٌ أَضَاعُوا۟ ٱلصَّلَوٰةَ وَٱتَّبَعُوا۟ ٱلشَّهَوَٰتِ فَسَوْفَ يَلْقَوْنَ غَيًّا

But after them there followed a posterity who missed prayers and followed after lusts soon, then, will they face Destruction,-

Sura al-Zukhruf 43:60

وَلَوْ نَشَآءُ لَجَعَلْنَا مِنكُم مَّلَٰٓئِكَةً فِى ٱلْأَرْضِ يَخْلُفُونَ

wa-law nashāʾu lajaʿalnā minkum malāʾikatan fī l-arḍi yakhlufūna

And if it were Our Will, We could make angels from amongst you, succeeding each other on the earth.
