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

God has bought from the believers their lives and their wealth because Paradise is for them. They fight for God’s cause. They slay and are slain. This promise is binding on Him in the Torah, the Gospel, and the Quran. Who is more faithful to his covenant than God? So, rejoice in the deal you’ve made. This is the ultimate triumph.
