1. 6:90 أُو۟لَٰٓئِكَ ٱلَّذِينَ هَدَى ٱللَّهُ فَبِهُدَىٰهُمُ ٱقْتَدِهْ قُل لَّآ أَسْـَٔلُكُمْ عَلَيْهِ أَجْرًا إِنْ هُوَ إِلَّا ذِكْرَىٰ لِلْعَٰلَمِينَ

   These are they whom Allah guided, therefore follow their guidance. Say: I do not ask you for any reward for it; it is nothing but a reminder to the nations.
   

2. 43:23 وَكَذَٰلِكَ مَآ أَرْسَلْنَا مِن قَبْلِكَ فِى قَرْيَةٍ مِّن نَّذِيرٍ إِلَّا قَالَ مُتْرَفُوهَآ إِنَّا وَجَدْنَآ ءَابَآءَنَا عَلَىٰٓ أُمَّةٍ وَإِنَّا عَلَىٰٓ ءَاثَٰرِهِم مُّقْتَدُونَ

   And thus, We did not send before you any warner in a town, but those who led easy lives in it said: Surely we found our fathers on a course, and surely we are followers of their footsteps.
