After describing varied fruits, rocks, people and animals, only those with knowledge truly fear Allah.
أَلَمۡ تَرَ أَنَّ ٱللَّهَ أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءࣰ فَأَخۡرَجۡنَا بِهِۦ ثَمَرَٰتࣲ مُّخۡتَلِفًا أَلۡوَٰنُهَاۚ وَمِنَ ٱلۡجِبَالِ جُدَدُۢ بِيضࣱ وَحُمۡرࣱ مُّخۡتَلِفٌ أَلۡوَٰنُهَا وَغَرَابِيبُ سُودࣱ ٢٧ وَمِنَ ٱلنَّاسِ وَٱلدَّوَآبِّ وَٱلۡأَنۡعَٰمِ مُخۡتَلِفٌ أَلۡوَٰنُهُۥ كَذَٰلِكَۗ إِنَّمَا يَخۡشَى ٱللَّهَ مِنۡ عِبَادِهِ ٱلۡعُلَمَٰٓؤُاْۗ إِنَّ ٱللَّهَ عَزِيزٌ غَفُورٌ ٢٨
27 Do you not see that Allah sends down rain from the sky, and We produce thereby fruits of varying colors? And in the mountains are tracts, white and red of varying shades and [some] extremely black 28 And among people and moving creatures and grazing livestock are various colors similarly. Only those fear Allah, from among His servants, who have knowledge. Indeed, Allah is Exalted in Might and Forgiving
