وَجَعَلْنَاكُمْ شُعُوبًا وَقَبَائِلَ لِتَعَارَفُوا
We made you peoples and tribes so that you may know one another.
The purpose lām in li-taʿārafū states the function of peoples and tribes: mutual recognition. The verse then relates honor to piety. Together the two parts distinguish social identification from the moral criterion of worth.
The text does not abolish recognition of ancestry or communities; it assigns social variety a constructive function while refusing to make lineage the final criterion of honor. Precision means preserving both halves.
