Allah created different races and tribes so that different peoples would recognize each other and learn from each other, not so that the races would fight each other.
Allah said:
يَا أَيُّهَا النَّاسُ إِنَّا خَلَقْنَاكُم مِّن ذَكَرٍ وَأُنثَىٰ وَجَعَلْنَاكُمْ شُعُوبًا وَقَبَائِلَ لِتَعَارَفُوا إِنَّ أَكْرَمَكُمْ عِندَ اللَّهِ أَتْقَاكُمْ إِنَّ اللَّهَ عَلِيمٌ خَبِيرٌ
O people, We have created you male and female and made you nations and tribes that you may know one another. Verily, the most noble of you to Allah is the most righteous of you. Verily, Allah is knowing and aware.
Surat Al-Hujurat 49:13
