‘Abd Allah bin Amr reported the Apostle of Allaah ﷺ as saying “No warlike party will go out to fight in Allaah’s path and gain booty without getting beforehand two-thirds of their rewards in the next world and one-third (of their reward) will remain. And if they do not gain booty, they will get their rewards in full.  

قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ غَازِيَةٍ تَغْزُو فِي سَبِيلِ اللَّهِ فَيُصِيبُونَ غَنِيمَةً إِلاَّ تَعَجَّلُوا ثُلُثَىْ أَجْرِهِمْ مِنَ الآخِرَةِ وَيَبْقَى لَهُمُ الثُّلُثُ فَإِنْ لَمْ يُصِيبُوا غَنِيمَةً تَمَّ لَهُمْ أَجْرُهُمْ
