Mustadrak al-Hakim — Hadith 8878

It is narrated from Qudamah bin Abdullah bin Ammar al-Kilabi that he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "It is binding upon you to fear Allah and to stay with this Jama'ah (the unity of the Muslims), for Allah Almighty will never unite the Ummah of Muhammad upon misguidance. And it is binding upon you to be patient until a righteous person finds rest or people find rest from a wicked person."
According to al-Hakim, this hadith has been written only through this chain, and one of its narrators, al-Husayn bin Dawud, does not meet the (strict) condition of this book.
