Thanks Br Shamim for the relevant verses.
The issue is how to react to injustice? Our own way or the Qur'anic way? If someone robs and kills an entire Muslims family, is the Muslim supposed to kill the robber, his entire family (along with a couple of innocent neighbours) or punish the guilty robber alone?
Unfavourable times for a Muslims are times of trial. It is either their way or the Qur'anic way.
