Musannaf Ibn Abi Shaybah 34566 — Reports on the virtue of Quraysh

Zayd bin Abi Attab (may Allah have mercy on him) said that Sayyiduna Mu'awiyah (may Allah be pleased with him) stood on the pulpit and said that the Prophet (peace and blessings be upon him) said: "People are followers of Quraysh in this matter of the caliphate. Those of Quraysh who were the best in the time of ignorance are the best in Islam as well, once they have been given understanding. By Allah, were it not that Quraysh would lose all restraint, I would tell them what the best of them have with Allah!"
