Qur'an 61:11

تُؤْمِنُونَ بِٱللَّهِ وَرَسُولِهِۦ وَتُجَـٰهِدُونَ فِى سَبِيلِ ٱللَّهِ بِأَمْوَٰلِكُمْ وَأَنفُسِكُمْ ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ

“[It is that] you believe in Allāh and His Messenger and strive in the cause of Allāh with your wealth and your lives. That is best for you, if you only knew.”
