O mankind! We have created you from a male and a female, and made you into NATIONS AND TRIBES, that you may know one another. Verily, the most honourable of you with Allah is that (believer) who has At-Taqwa [i.e. he is one of the Muttaqun (the pious. See V.2:2)]. Verily, Allah is All-Knowing, All-Aware.
( سورة الØ*جرات , Al-Hujraat, Chapter #49, Verse #13)
And among His Signs is the creation of the heavens and the earth, and the difference of your LANGUAGES and colours. Verily, in that are indeed signs for men of sound knowledge.
( سورة الروم , Ar-Room, Chapter #30, Verse #22)
