Nasai

´It was narrated from Shu'bah, from Sayyar and Yahya bin Sa'eed that they heard 'Ubadah bin Al-Walid narrating from his father. Sayyar said:` "From his father," and Yahya said: "From his father," from his grandfather, whom said: 'We pledged to the Messenger of Allah to hear and obey during our hardship and our ease, when we felt energetic and when we felt tired, and when others are preferred over us, that we would not contend with the orders of whomever was entrusted with it, that we would stand firm for the truth wherever it may be, and that we would not fear the blame of any blamer for the sake of Allah." (Sahih) Shu'bah said: "Sayyar did not mention this statement: 'Wherever it may be' while Yahya mentioned it." Shu'bah said: "If I have added anything to it, then it is from Sayyar or from Yahya."

´It was narrated from Abu Hurairah that the Messenger of Allah said:` "You have to obey when you feel energetic and when you feel tired, during your ease and your hardship, and when others are preferred over you."
