Sayyiduna Bishr bin Ismah (may Allah be pleased with him), a Companion of the Prophet (peace and blessings be upon him), said that the Messenger of Allah (peace and blessings be upon him) said: "Al-Azd are from me and I am from them. When they are angered, I am angered for them, and when they are pleased, I am pleased for them." Then Mu'awiyah (may Allah have mercy on him) said: He (peace and blessings be upon him) said that about Quraysh. Bishr (may Allah be pleased with him) said: "Would I lie about the Messenger of Allah (peace and blessings be upon him)? Had I lied about him, I would have attributed it to my own people."
