At Tawbah Ayah 41

ٱنفِرُواْ خِفَافًا وَثِقَالاً وَجَـٰهِدُواْ بِأَمْوَٲلِكُمْ وَأَنفُسِكُمْ فِى سَبِيلِ ٱللَّهِ‌ۚ ذَٲلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ ٤١ ?O believers!? March forth whether it is easy or difficult for you, and strive with your wealth and your lives in the cause of Allah. That is best for you, if only you knew.
