A troop of soldiers who fight in tile way of Allah and get their share of the booty receive in advance two-thirds of their reward in the Hereafter and only one-third will remain (to their credit). If they do not receive any booty, they will get their full reward.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَا مِنْ غَازِيَةٍ تَغْزُو فِي سَبِيلِ اللَّهِ فَيُصِيبُونَ الْغَنِيمَةَ إِلاَّ تَعَجَّلُوا ثُلُثَىْ أَجْرِهِمْ مِنَ الآخِرَةِ وَيَبْقَى لَهُمُ الثُّلُثُ وَإِنْ لَمْ يُصِيبُوا غَنِيمَةً تَمَّ لَهُمْ أَجْرُهُمْ
