do not be faint of heart in pursuing these people if you happen to suffer harm they too are suffering just as you are while you may hope from allah what they cannot hope for. allah is allknowing all wise.
ولا تهنوا في ابتغاء القوم إن تكونوا تألمون فإنهم يألمون كما تألمون وترجون من الله ما لا يرجون وكان الله عليما حكيما
