Musnad Abu Ya'la al-Mawsili 110:82

Zuhayr narrated to us, Ibn ‘Uyaynah narrated to us, from Sulayman al-Ahwal, from Sa‘id ibn Jubayr, from Ibn ‘Abbas, who said: "Thursday, and what is Thursday? The pain of the Messenger of Allah (may Allah bless him and grant him peace) intensified on Thursday. He said: 'Bring me [writing materials] so that I may write for you a document after which you will never go astray.' They disputed, and disputing in the presence of a Prophet is not appropriate. He said: 'Leave me, for what I am in is better than what you are asking me about.' He commanded them with three things: He said: 'Expel the polytheists from the Arabian Peninsula, and give gifts to the delegations in the same manner as I used to give them.' And the third one, I do not know if he said it and I forgot it, or if he did not say it."
