Silsilah as-Sahihah 2754 — Superiority is by good deeds; bad speech

It is narrated from Sayyiduna Uqbah bin Amir al-Juhani (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: “These lineages of yours are not a cause of reproach or disgrace for anyone, because you are all the children of Adam, and you are less than a full measure (i.e., none of you is perfect and everyone 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) that he is foul-mouthed, ill-spoken, ill-mannered, miserly, and cowardly.”
