The believers must help and defend themselves when an oppressive wrong is inflicted on them!

Verses 36-39 pf Chapter 42:

Whatever ye are given (here) is (but) a convenience of this life: but that which is with Allah is better and more lasting: (it is) for those who believe and put their trust in their Lord: Those who avoid the greater crimes and shameful deeds, and, when they are angry even then forgive; Those who hearken to their Lord, and establish regular Prayer; who (conduct) their affairs by mutual Consultation; who spend out of what We bestow on them for Sustenance; And those who, when an oppressive wrong is inflicted on them, (are not cowed but) help and defend themselves.
