The Messenger of Allah's ﷺ she-camel, Adba, was never outrun. Then a bedouin came on a young camel and outran her. The Messenger of Allah ﷺ said, "It is a right upon Allah that He does not raise anything in this world except that He brings it low."
كانت ناقة رسول الله ﷺ العضباء لا تسبق، فجاء اعرابي على قعود فسبقها، فقال رسول الله ﷺ: حقا على الله لا يرفع شيئا من الدنيا إلا وضعه.
Bazzar (7700) and Daraqutni (4826–4828) both narrated it through chains going back to Maen bin Isa, who said, Malik bin Anas narrated to us, from Ibn Shihab Zuhri, from Saeed bin Musayab, from Abu Hurairah, and he mentioned it. Its chain of transmission is sahih.This hadith has also been narrated from Malik as mursal, but this does not harm it, because a narrator may connect a hadith when he is energetic, and sometimes narrate it as mursal when he lacks energy. Bazzar said, "We do not know of anyone who raised this hadith to the Prophet except Malik, nor of anyone who narrated it from him except Maen. Maen said, Malik used to not attribute it with a full chain, but one day he came out to us energetic, and narrated it to us from Zuhri, from Saeed, from Abu Hurairah."
