Quran 61:11 As-Saff, ayah 11 of 14

تُؤْمِنُونَ بِٱللَّهِ وَرَسُولِهِۦ وَتُجَـٰهِدُونَ فِى سَبِيلِ ٱللَّهِ بِأَمْوَٰلِكُمْ وَأَنفُسِكُمْ ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ ۝١١

61:11 Ye should believe in Allah and His messenger, and should strive for the cause of Allah with your wealth and your lives. That is better for you, if ye did but know.
