O humankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the noblest of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted
(Surah Al-Hujurat, 49:13)
Hadith:
Reported by Aisha r.a: It was the day of Eid and the Abyssinians were playing with shields and spears (a cultural performance). Either I asked the Prophet or he asked me whether I would like to watch and I said yes. Then, the Prophet made me stand behind him while my cheek was touching his cheek and the Prophet was saying, “Carry on, O tribe of Arfidah.”
