i hope you both are talking about this specific ayat :
"Oh mankind" and it says that He Allah has "created you from a single source and has created you in nations and tribes, **not that you may discriminate against one another, but that you may know one another.* Verily the most honoured of you in the sight of Allah is (he who is) the most righteous of you***
Surah Hujarah (49) ayah 13.
the bold in red is the actual message in the ayah .. let's keep that in mind for the context of black in bold.
Thanks for sharing it.
