Sayyiduna Ya'la bin Munyah (may Allah be pleased with him) said: The Prophet (peace and blessings be upon him) used to send me on campaigns. Once he (peace and blessings be upon him) sent me out, and a man used to saddle my mount for me. I said to him: Saddle up and let us go. He said: I will not go with you. I said: Why? He said: Not until you fix three dinars for me. I said: Now I have already set out and I will not go back to him (peace and blessings be upon him); saddle up and you will get three dinars. When I returned from the campaign, I mentioned this to him (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: "Give them to him; this is his share from the campaign."
