إِنَّ اللَّهَ اشتَرىٰ مِنَ المُؤمِنينَ أَنفُسَهُم وَأَموالَهُم بِأَنَّ لَهُمُ الجَنَّةَ ۚ يُقاتِلونَ في سَبيلِ اللَّهِ فَيَقتُلونَ وَيُقتَلونَ ۖ وَعدًا عَلَيهِ حَقًّا فِي التَّوراةِ وَالإِنجيلِ وَالقُرآنِ ۚ وَمَن أَوفىٰ بِعَهدِهِ مِنَ اللَّهِ ۚ فَاستَبشِروا بِبَيعِكُمُ الَّذي بايَعتُم بِهِ ۚ وَذٰلِكَ هُوَ الفَوزُ العَظيمُ

Indeed, Allah has purchased from the believers their lives and their properties [in exchange] for that they will have Paradise. They fight in the cause of Allah, so they kill and are killed. [It is] a true promise [binding] upon Him in the Torah and the Gospel and the Qur'an. And who is truer to his covenant than Allah? So rejoice in your transaction which you have contracted. And it is that which is the great attainment.
