All those people who say that castes are stupid,bull****, yeh its stupid and bull**** if you make it into a segregation issue, but its still good to know your family history,background and roots, i am proud of my history, but i dont think im superior than others, yeah some ppl do but thats their messed up ignorance.
Allah describes in the quran that he made us into different tribes so we can come to meet each other, thus its not a bad thing knowing where you come from aslong as you dont make it into a issue of a ranking system, infact its a good thing as it shows diversity and shows how islam has put different people from different tribes,nations groups under one banner.
Qur'an 49:13
O mankind!
We created you from a single (pair) of a male and a female
And made you into nations and tribes
That ye may know each other (not that ye may despise each other).
Verily the most honored of you in the sight of Allah is (he who is) the most righteous of you.
And Allah has full knowledge and is well acquainted (with all things).
