Musnad Ahmad 25:682

'Affan narrated to us, he said: Hammad bin Zayd narrated to us, 'Amr bin Dinar informed us, that Tawus said: He who is more knowledgeable about it than them narrated to me—meaning 'Abdullah bin 'Abbas—that the Messenger of Allah, peace and blessings of Allah be upon him, said: "For a man to grant his brother his land is better for him than that he should take a known tribute for it."
