Sunan Abi Dawud Book 15, Hadith 59
The Messenger of Allah (ﷺ) sent us on foot to get spoil, but we returned without getting any. When he saw the signs of distress on our faces, he stood up on our faces and said: O Allah, do not put them under my care, for I would be too weak to care for them; do not put them in care of themselves, for they would be incapable of that, and do not put them in the care of men, for they would choose the best things for themselves. He then placed his hand on my head and said: Ibn Hawalah, when you see the caliphate has settled in the holy land, earthquakes, sorrows and serious matters will have drawn near and on that day the Last Hour will be nearer to mankind than this hand of mine is to your head.
Abu Dawud said: 'Abd Allah b. Hawalah belongs to Hims.
Once the Messenger of Allah (ﷺ) intended to go on an expedition. He said: O group of the emigrants (Muhajirun) and the helpers (Ansar), among your brethren there are people who have neither property nor family. So one of you should take with him two or three persons; with me. I also rode on my camel by turns like one of them.
The Prophet (ﷺ) said: Our Lord Most High is pleased with a man who fights in the path of Allah, the Exalted; then his companions fled away (i.e. retreated). But he knew that it was a sin (to flee away from the battlefield), so he returned, and his blood was shed. Thereupon Allah, the Exalted, says to His angels: Look at My servant; he returned seeking what I have for him (i.e. the reward), and fearing (the punishment) I have, until his blood was shed.
