At Tawbah Ayah 111

۞ إِنَّ ٱللَّهَ ٱشْتَرَىٰ مِنَ ٱلْمُؤْمِنِينَ أَنفُسَهُمْ وَأَمْوَٲلَهُم بِأَنَّ لَهُمُ ٱلْجَنَّةَ‌ۚ يُقَـٰتِلُونَ فِى سَبِيلِ ٱللَّهِ فَيَقْتُلُونَ وَيُقْتَلُونَ‌ۖ وَعْدًا عَلَيْهِ حَقًّا فِى ٱلتَّوْرَٮٰةِ وَٱلْإِنجِيلِ وَٱلْقُرْءَانِ‌ۚ وَمَنْ أَوْفَىٰ بِعَهْدِهِۦ مِنَ ٱللَّهِ‌ۚ فَٱسْتَبْشِرُواْ بِبَيْعِكُمُ ٱلَّذِى بَايَعْتُم بِهِۦ‌ۚ وَذَٲلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ ١١١ Allah has indeed purchased from the believers their lives and wealth in exchange for Paradise. They fight in the cause of Allah and kill or are killed. This is a true promise binding on Him in the Torah, the Gospel, and the Quran. And whose promise is truer than Allah’s? So rejoice in the exchange you have made with Him. That is ?truly? the ultimate triumph.
