Retribution For Mocking
Its a tricky question coz Allah has given permission to take revenge as eye for eye etc on the other hand Quran has explicitly advised muslims to avoid calling others bad name and ridicule them in 49:11. Its better to ignore and forgive them
You know it very well that I refrain from commenting on hypothetical scenarios. I have stated my advice in principle. What decisions person X and person Y make are immaterial to me.
