تُؤْمِنُونَ بِاللَّهِ وَرَسُولِهِ وَتُجَاهِدُونَ فِي سَبِيلِ اللَّهِ بِأَمْوَالِكُمْ وَأَنفُسِكُمْ ذَلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ
[It is that] you believe in Allah and His Messenger and strive in the cause of Allah with your wealth and your lives. That is best for you, if you should know.
