Narrated Ya'la ibn Munyah:

The Messenger of Allah ﷺ 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 ﷺ 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.

حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي عَاصِمُ بْنُ حَكِيمٍ، عَنْ يَحْيَى بْنِ أَبِي عَمْرٍو السَّيْبَانِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ الدَّيْلَمِيِّ، أَنَّ يَعْلَى بْنَ مُنْيَةَ، قَالَ : آذَنَ رَسُولُ اللَّهِ ﷺ بِالْغَزْوِ وَأَنَا شَيْخٌ كَبِيرٌ لَيْسَ لِي خَادِمٌ، فَالْتَمَسْتُ أَجِيرًا يَكْفِينِي وَأُجْرِي لَهُ سَهْمَهُ، فَوَجَدْتُ رَجُلاً، فَلَمَّا دَنَا الرَّحِيلُ أَتَانِي فَقَالَ : مَا أَدْرِي مَا السُّهْمَانُ وَمَا يَبْلُغُ سَهْمِي فَسَمِّ لِي شَيْئًا كَانَ السَّهْمُ أَوْ لَمْ يَكُنْ . فَسَمَّيْتُ لَهُ ثَلاَثَةَ دَنَانِيرَ، فَلَمَّا حَضَرَتْ غَنِيمَتُهُ أَرَدْتُ أَنْ أُجْرِيَ لَهُ سَهْمَهُ، فَذَكَرْتُ الدَّنَانِيرَ، فَجِئْتُ النَّبِيَّ ﷺ فَذَكَرْتُ لَهُ أَمْرَهُ، فَقَالَ :
" مَا أَجِدُ لَهُ فِي غَزْوَتِهِ هَذِهِ فِي الدُّنْيَا وَالآخِرَةِ إِلاَّ دَنَانِيرَهُ الَّتِي سَمَّى " .
