Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "Beware of the supplication of the oppressed." (Imam Ibn Hibban, may Allah have mercy on him, says:) The statement of the Prophet Muhammad (peace and blessings be upon him): "Beware of the supplication of the oppressed"—here, he has commanded to avoid the supplication of the oppressed, but what is meant is to refrain from that thing which results in this supplication, and that thing is oppression. Here, the Prophet Muhammad (peace and blessings be upon him) has, by commanding to refrain from one thing, actually commanded to stay away from that which leads to it.
