It is narrated from Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever goes on a military expedition (in the path of Allah) intending nothing from it but a rope ('iqal, for tying a camel), he will have only what he intended." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Ya'la bin Munyah (may Allah be pleased with him) that he said: The Prophet (peace and blessings be upon him) used to send me out in his military detachments (saraya). One day he (peace and blessings be upon him) sent me, and a man was going to ride my mule. I said to him: "Set off (let us depart)." He said: "I will not go out with you." I asked: "Why?" He said: "Not until you fix three dinars for me." I said (to myself): "Now, when I have already bid farewell to the Prophet (peace and blessings be upon him), I am not going back to him again." (So I said to him:) "Go, and you have three dinars (agreed)." Then when I returned from my expedition, I mentioned that to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: "Give it to him, for that alone is his (otherworldly) share from his expedition."
