Musnad Ahmad 31:841

Yahya ibn Abi Bukayr narrated to us, al-Fudayl ibn Marzuq narrated to us, from Atiyyah al-Awfi, who said: Abu Sa’id said: A man from the Ansar said to his companions: "By Allah, I used to tell you that if matters were to become established, he would prefer others over you." He said: So they replied to him with a harsh reply. He said: That reached the Messenger of Allah, peace and blessings of Allah be upon him. He said: So he came to them and said things to them that I do not remember. They said: "Yes, O Messenger of Allah." He said: "And you would not ride horses?" He said: So every time he said something to them, they said: "Yes, O Messenger of Allah." He said: So when he saw that they were not replying to him with anything, he said: "Will you not say: 'Your people fought you, so we gave you victory; and your people expelled you, so we gave you shelter'?" They said: "We will not say that, O Messenger of Allah; you say it." He said: "O assembly of Ansar, are you not pleased that the people go away with the world, while you go away with the Messenger of Allah?" They said: "Yes, O Messenger of Allah." He said: "O assembly of Ansar, are you not pleased that if the people traveled through a valley and you traveled through a valley, I would travel through the valley of the Ansar?" They said: "Yes, O Messenger of Allah." He said: "Were it not for the Hijrah, I would have been a man from the Ansar, like my kin, my household, and my inner circle to whom I take refuge. So pardon those among them who do wrong, and accept from those among them who do good." Abu Sa’id said: I said to Mu’awiyah: "Indeed, the Messenger of Allah, peace and blessings of Allah be upon him, told us that we would see favoritism after him." Mu’awiyah said: "So what did he command you?" I said: "He commanded us to be patient." He said: "Then be patient."
