Surah At-Taubah (The Repentance), Verse 111

اِنَّ اللّٰهَ اشْتَرٰی مِنَ الْمُؤْمِنِیْنَ اَنْفُسَهُمْ وَاَمْوَالَهُمْ بِاَنَّ لَهُمُ الْجَنَّةَ یُقَاتِلُوْنَ فِیْ سَبِیْلِ اللّٰهِ فَیَقْتُلُوْنَ وَیُقْتَلُوْنَ وَعْدًا عَلَیْهِ حَقًّا فِی التَّوْرٰىةِ وَالْاِنْجِیْلِ وَالْقُرْاٰنِ وَمَنْ اَوْفٰی بِعَهْدِهٖ مِنَ اللّٰهِ فَاسْتَبْشِرُوْا بِبَیْعِكُمُ الَّذِیْ بَایَعْتُمْ بِهٖ وَذٰلِكَ هُوَ الْفَوْزُ الْعَظِیْمُ ۟

Innal laahash taraa minal mu'mineena anfusahum wa amwaalahum bi anna lahumul jannah; yuqaatiloona fee sabeelil laahi fa yaqtuloona wa yuqtaloona wa'dan 'alaihi haqqan fit Tawraati wal Injeeli wal Qur'aaan; wa man awfaa bi'ahdihee minal laah; fastabshiroo bi bay'ikumul lazee baaya'tum bih; wa zaalika huwal fawzul 'azeem

“Allah hath purchased of the believers their persons and their goods; for theirs (in return) is the garden (of Paradise): they fight in His cause, and slay and are slain: a promise binding on Him in truth, through the Law, the Gospel, and the Qur'an: and who is more faithful to his covenant than Allah? then rejoice in the bargain which ye have concluded: that is the achievement supreme.”
