Here are some of them:

 

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 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).

35:28 And so amongst men and crawling creatures and cattle, are they of various colours. Those truly fear Allah, among His Servants, who have knowledge: for Allah is Exalted in Might, Oft-Forgiving.

 

30:22 (Y. Ali) And among His Signs is the creation of the heavens and the earth, and the variations in your languages and your colours: verily in that are Signs for those who know.

 

5:48�To each among you have We prescribed a Law and an Open Way. If Allah had so willed, He would have made you a single People, but (His plan is) to test you in what He has given you; so strive as in a race in all virtues. The goal of you all is to Allah; it is He that will show you the truth of the matters in which ye dispute.

109:6 To you be your Way, and to me mine. --- This talk about tolerance

 

2:256 �Let there be no compulsion in religion.  Truth has been made clear from error.  Whoever rejects false worship and believes in God has grasped the most trustworthy handhold that never breaks.  And God hears and knows all things.�
