O people! Your God is one and your forefather (Adam) is one. An Arab is not better than a non-Arab and a non-Arab is not better than an Arab, and a red (i. e. white tinged with red) person is not better than a black person and a black person is not better than a red person, except in piety.

Narrated in Mosnad Ahmad, #22978 - Sunni Hadith
