A: The ruling on this is found in the Ayah (Qur'anice verse) of Allah (Glorified be He): 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 Allâh is that (believer) who has At-Taqwâ [i.e. he is one of the Muttaqûn (the pious. See V.2:2)].

Thus, if a non-Arab has more Taqwa (fearing Allah as He should be feared), in this case they will be the superior, and vice versa. Merit, honor, and esteem is achieved by having Taqwa. Therefore, whoever has the most Taqwa is superior before Allah, whether Arab or non-Arab.
