"I heard the Messenger of Allah ﷺ say: 'There is no raiding party that goes out in the cause of Allah and acquires some spoils of war, but they have been given two-thirds of their reward in this world instead of in the Hereafter, and there remains one-third (in the Hereafter). And if they do not acquire any spoils of war, then all of their reward (will come in the Hereafter).'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ 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  

"And of My slaves who goes out as a Mujahid striving in the cause of Allah, seeking my pleasure, I guarantee that I will bring him back with whatever he had earned as reward or spoils of war, and if I take his (soul) I will forgive him and have mercy on him."  

عَنِ النَّبِيِّ ﷺ فِيمَا يَحْكِيهِ عَنْ رَبِّهِ ﷻ قَالَ أَيُّمَا عَبْدٍ مِنْ عِبَادِي خَرَجَ مُجَاهِدًا فِي سَبِيلِ اللَّهِ ابْتِغَاءَ مَرْضَاتِي ضَمِنْتُ لَهُ أَنْ أَرْجَعَهُ إِنْ أَرْجَعْتُهُ بِمَا أَصَابَ مِنْ أَجْرٍ أَوْ غَنِيمَةٍ وَإِنْ قَبَضْتُهُ غَفَرْتُ لَهُ وَرَحِمْتُهُ
