Mishkat al-Masabih 3844
Ya‘la. b. Umayya said:
God’s Messenger announced an expedition, and as I was a very old man who had no servant I sought a hireling who would serve instead of me. I found a man to whom I offered three dinars, and when some booty arrived I wanted to give him his portion, so I went to the Prophet and mentioned the matter to him, but he said, “All I can find for him regarding this expedition of his in this world and the next is the three dinars which were offered him." 

Abu Dawud transmitted it.
وَعَن يَعْلى بن أُميَّةَ قَالَ: أَذِنَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بالغزو وَأَن شَيْخٌ كَبِيرٌ لَيْسَ لِي خَادِمٌ فَالْتَمَسْتُ أَجِيرًا يَكْفِينِي فَوَجَدْتُ رَجُلًا سَمَّيْتُ لَهُ ثَلَاثَةَ دَنَانِيرَ فَلَمَّا حَضَرَتْ غَنِيمَةٌ أَرَدْتُ أَنْ أُجْرِيَ لَهُ سَهْمَهُ فَجِئْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَذَكَرَتْ لَهُ فَقَالَ: «مَا أَجِدُ لَهُ فِي غَزْوَتِهِ هَذِهِ فِي الدُّنْيَا وَالْآخِرَةِ إِلَّا دَنَانِيرَهُ الَّتِي تسمى» . رَوَاهُ أَبُو دَاوُد
