Salaam o 'alykum warahmatulahi wabarakatuh.
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 honoured 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). (49:13)
...Allah is sufficient for you; He it is Who strengthened you with His help and with the believers (8:62)
And united their hearts; had you spent all that is in the earth, you could not have united their hearts, but Allah united them; surely He is Mighty, Wise. (8:63)
wa Salaam o 'alykum warahmatulahi wabarakatuh.
