Sunnan Abu Dawud Collection: ::Book Number 14:: Hadith # 2521
Narrated Ya'la ibn Munyah: The Apostle of Allah (peace_be_upon_him) announced an expedition, and I was a very old man and I had no servant. I, therefore, sought a hireling who would serve instead of me, and I would give him his portion. So I found a man. When the time of departure arrived, he came to me and said: I do not know what would be the portions, and how much would be my portion. So offer something (as wages) to me, whether there would be any portion or not. I offered three dinars (as his wages) for him. When some booty arrived, I wanted to offer him his portion. But I remembered the dinars, so I went to the Prophet (peace_be_upon_him) and mentioned the matter to him. He said: All I can find for him regarding this expedition of his in this world and the next is three dinars which were offered him.
