Musnad Ahmad 25:149

Yahya narrated to us, from Habib ibn Shihab, my father narrated to me, he said: I heard Ibn Abbas saying: The Messenger of Allah, peace and blessings of Allah be upon him, said on the day he addressed the people at Tabuk: "There is no one among the people like a man who takes hold of the head of his horse, striving in the way of Allah, the Almighty and Majestic, and avoiding the evils of the people. And [there is no one like] another who is in the desert in prosperity, hosting his guest and giving [what is due of] his right."
