﴿ ۞ إِنَّ ٱللَّهَ ٱشْتَرَىٰ مِنَ ٱلْمُؤْمِنِينَ أَنفُسَهُمْ وَأَمْوَٰلَهُم بِأَنَّ لَهُمُ ٱلْجَنَّةَ ۚ يُقَٰتِلُونَ فِى سَبِيلِ ٱللَّهِ فَيَقْتُلُونَ وَيُقْتَلُونَ ۖ وَعْدًا عَلَيْهِ حَقًّۭا فِى ٱلتَّوْرَىٰةِ وَٱلْإِنجِيلِ وَٱلْقُرْءَانِ ۚ وَمَنْ أَوْفَىٰ بِعَهْدِهِۦ مِنَ ٱللَّهِ ۚ فَٱسْتَبْشِرُوا۟ بِبَيْعِكُمُ ٱلَّذِى بَايَعْتُم بِهِۦ ۚ وَذَٰلِكَ هُوَ ٱلْفَوْزُ ٱلْعَظِيمُ ﴾

“BEHOLD, God has bought of the believers their lives and their possessions, promising them paradise in return, [and so] they fight in God's cause, and slay, and are slain: a promise which in truth He has willed upon Himself in [the words of] the Torah, and the Gospel, and the Qur'an. And who could be more faithful to his covenant than God? Rejoice, then, in the bargain which you have made with Him: for this, this is the triumph supreme!”

(Lo! Allah hath bought from the believers) who are sincere (their lives and their wealth because the Garden will be theirs) in exchange for the Garden (they shall fight in the way of Allah) in obedience of Allah (and shall slay) the enemy (and be slain) by the enemy. (It is a promise) from Allah (which is binding on Him) that He must fulfil (in the Torah and the Gospel and the Qur'an. Who fulfilleth His covenant better than Allah? Rejoice then in your bargain that ye have made) with Allah, i.e. the Garden, (for that is the Supreme Triumph) the abounding safety.
