It is narrated from al-Hasan al-Basri that Sayyiduna A'idh bin Amr (may Allah be pleased with him) said to Ziyad: It used to be said to us: "The worst of rulers are those who crush; beware lest you be one of them." Ziyad said to him: You are only from the chaff of the Companions of Muhammad (peace and blessings be upon him).
