Narrated by Hazrat Uqbah bin Amir Juhani (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Surely your lineage is not a cause of disgrace or shame for anyone, because you are all the children of Adam, and you are less than a full measure (that is, none of you is complete and perfect, each one has some deficiency). And no one has any superiority or excellence over another except on the basis of religion and righteous deeds. It is sufficient for a man to be considered bad if he is foul-mouthed, ill-spoken, ill-mannered, miserly, and cowardly.
