Musannaf Ibn Abi Shaybah

Hazrat Rabi’ah bin Najid, may Allah have mercy on him, narrates that Hazrat Ali, may Allah be pleased with him, said: Verily, the Quraysh are the leaders of the Arabs. And their righteous people are the leaders of the righteous. And their evil people are the leaders of the evildoers. And everyone has a right. So give each rightful person his due.
