It is narrated from Ahnaf bin Qais (may Allah have mercy on him) that once his cousin presented himself in the court of the Messenger and said, "O Messenger of Allah! Give me some brief advice, perhaps I will understand it." The Noble Prophet (peace and blessings be upon him) said, "Do not get angry." He repeated his request several times, and the Noble Prophet (peace and blessings be upon him) gave the same reply each time: "Do not get angry."
