Sayyiduna Uqbah bin Amir (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "These lineages of yours are not such that you should revile anyone on account of them. You are the children of Sayyiduna Adam (peace be upon him), a sa' measure falling short that you cannot fill (that is, every human being has some deficiency and shortcoming). No one has any superiority over anyone else, except for superiority in religion or righteous deeds. And it is enough (evil) for a man that he is obscene in speech, foul-tongued, miserly or cowardly."
