21:28
يَعْلَمُ مَا بَيْنَ أَيْدِي هِمْ وَ مَا خَلْفَ هُمْ وَ لَا يَشْفَعُ ونَ إِلَّا لِ مَنِ ٱرْتَضَىٰ وَ هُم مِّنْ خَشْيَتِ هِۦ مُشْفِقُونَ
He knows what is [presently] before them and what will be after them, and they cannot intercede except on behalf of one whom He approves. And they, from fear of Him, are apprehensive.
24:55
وَعَدَ ٱللَّهُ ٱلَّذِينَ ءَامَنُ وا۟ مِن كُمْ وَ عَمِلُ وا۟ ٱل صَّٰلِحَٰتِ لَ يَسْتَخْلِفَ نَّ هُمْ فِى ٱلْ أَرْضِ كَ مَا ٱسْتَخْلَفَ ٱلَّذِينَ مِن قَبْلِ هِمْ وَ لَ يُمَكِّنَ نَّ لَ هُمْ دِينَ هُمُ ٱلَّذِى ٱرْتَضَىٰ لَ هُمْ وَ لَ يُبَدِّلَ نَّ هُم مِّنۢ بَعْدِ خَوْفِ هِمْ أَمْنًا يَعْبُدُ ونَ نِى لَا يُشْرِكُ ونَ بِ ى شَيْـًٔا وَ مَن كَفَرَ بَعْدَ ذَٰلِكَ فَ أُو۟لَٰٓئِكَ هُمُ ٱلْ فَٰسِقُونَ
Allah has promised those who have believed among you and done righteous deeds that He will surely grant them succession [to authority] upon the earth just as He granted it to those before them and that He will surely establish for them [therein] their religion which He has preferred for them and that He will surely substitute for them, after their fear, security, [for] they worship Me, not associating anything with Me. But whoever disbelieves after that - then those are the defiantly disobedient.
72:27
إِلَّا مَنِ ٱرْتَضَىٰ مِن رَّسُولٍ فَ إِنَّ هُۥ يَسْلُكُ مِنۢ بَيْنِ يَدَيْ هِ وَ مِنْ خَلْفِ هِۦ رَصَدًا
Except whom He has approved of messengers, and indeed, He sends before each messenger and behind him observers
