وَعَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا مِنْ غَازِيَة أَو سَرِيَّة تغزو فتغتنم وَتَسْلَمُ إِلَّا كَانُوا قَدْ تَعَجَّلُوا ثُلُثَيْ أُجُورِهِمْ وَمَا مِنْ غَازِيَةٍ أَوْ سَرِيَّةٍ تَخْفُقُ وَتُصَابُ إِلَّا تمّ أُجُورهم» . رَوَاهُ مُسلم
English Translation
‘Abdallah b. ‘Amr reported God’s Messenger as saying, “No war-like party or body of troops will go out to fight, gain booty and return safe without getting beforehand two-thirds of their rewards,* and no war-like party or body of troops will be disappointed of their hopes and be smitten without getting their rewards in full.” * The suggestion is made that the two-thirds are a safe return and booty which they get in this world, the remaining third being reward in the next. Muslim transmitted it.
