Allah the Exalted said: 0 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 honorable of you in the Sight of Allah is that (believer) who has At-Taqwa i.e., one of the Muttaqun: i.e., pious and righteous persons who fear Allah much (abstain from all kinds of sins and evil deeds which He has forbidden), and love Allah much (perform all kinds of good deeds which He has ordained). Verily Allah is All-Knowing, All-Aware. " Surah 49: 13
