وَلا تَهِنوا فِي ابتِغاءِ القَومِ ۖ إِن تَكونوا تَألَمونَ فَإِنَّهُم يَألَمونَ كَما تَألَمونَ ۖ وَتَرجونَ مِنَ اللَّهِ ما لا يَرجونَ ۗ وَكانَ اللَّهُ عَليمًا حَكيمًا

And do not weaken in pursuit of the enemy. If you should be suffering - so are they suffering as you are suffering, but you expect from Allah that which they expect not. And Allah is ever Knowing and Wise.
