The people are from Aadam, & Aadam was from earth
Allaah's Messenger sallallaahu 'alayhi wa sallam said: "Indeed there is no excellence for an arab over a non-arab, nor for a non-arab over on arab, nor for a white person over a black one, nor for a black person over a white one, except through taqwaa (piety and obedience to Allaah). The people are from Aadam, and Aadam was from earth."(Ahmed) The Prophet sallallaahu 'alayhi wa sallam also said: "Indeed my awliyaa (friends and allies) are not the tribe of so and so. Rather my friends and allies are the muttaqoon (those who possess taqwaa) - wherever they may be.(Bukhari, Muslim)
