حَدَّثَنِي مُحَمَّدُ بْنُ سَهْلٍ التَّمِيمِيُّ، حَدَّثَنَا ابْنُ أَبِي مَرْيَمَ، أَخْبَرَنَا نَافِعُ بْنُ يَزِيدَ، حَدَّثَنِي أَبُو هَانِئٍ، حَدَّثَنِي أَبُو عَبْدِ الرَّحْمَنِ الْحُبُلِيُّ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَا مِنْ غَازِيَةٍ أَوْ سَرِيَّةٍ تَغْزُو فَتَغْنَمُ وَتَسْلَمُ إِلاَّ كَانُوا قَدْ تَعَجَّلُوا ثُلُثَىْ أُجُورِهِمْ وَمَا مِنْ غَازِيَةٍ أَوْ سَرِيَّةٍ تُخْفِقُ وَتُصَابُ إِلاَّ تَمَّ أُجُورُهُمْ " .
It has been narrated on the authority of Abdullah b. Amr (through a different chain of transmitters) that the Messenger of Allah (PBUH) said: A troop of soldiers, large or small, who fight (in the way of Allah), get their share of the booty and return safe and sound, receive in advance two-thirds of their reward (only one-third remaining to their credit to be received in the Hereafter) ; and a troop of soldiers, large or small, who return empty-handed and are afflicted or wounded, will receive their full reward (in the Hereafter).
