Fatir - 35:28

وَمِنَ النَّاسِ وَالدَّوَابِّ وَالْأَنْعَامِ مُخْتَلِفٌ أَلْوَانُهُ كَذَلِكَ إِنَّمَا يَخْشَى اللَّهَ مِنْ عِبَادِهِ الْعُلَمَاء إِنَّ اللَّهَ عَزِيزٌ غَفُورٌ
[35:28]
And of men and beasts and cattle are various species of it likewise; those of His servants only who are possessed of knowledge fear Allah; surely Allah is Mighty, Forgiving.
And so amongst men and crawling creatures and cattle, are they of various colours. Those truly fear Allah, among His Servants, who have knowledge: for Allah is Exalted in Might, Oft-Forgiving.
And of men and beasts and cattle, in like manner, divers hues? The erudite among His bondmen fear Allah alone. Lo! Allah is Mighty, Forgiving.
