The Messenger of Allah ﷺ said, "The Hour will not come until the earth is filled with injustice and aggression. Then a man from my offspring," or he said, "from my household, will emerge and fill it with fairness and justice just as it had been filled with injustice and aggression."
قال رسول الله ﷺ: لا تقوم الساعة حتى تمتلئ الأرض ظلما وعدوانا، قال: ثم يخرج رجل من عترتي أو من أهل بيتي يملؤها قسطا وعدلا كما ملئت ظلما وعدوانا.
Ahmad (11313) narrated it, and Ibn Hibban (6823) and Hakim (4/557) graded it sahih, all of them through various routes from Awf bin Abu Jameela, from Abu Siddiq Naji, from Abu Saeed Khudri, who related it. Its chain of transmission is sahih. Hakim said, "This is a sahih hadith according to the criteria of the two Shaikhs."
