Musannaf Ibn Abi Shaybah

Hazrat Ubadah bin Samit said to Hazrat Junadah bin Abu Umayyah Ansari, "Come, I will inform you what is for you and what is obligatory upon you: to listen and obey in your hardship and ease, in happiness and displeasure, and even when preference is given over you, and that you should not speak out or dispute with the rulers unless you see clear disbelief."
