One of the beautiful names of Allah swt is Ash Shaheed- The Witness.
Oppression done by Oppressors, betrayal by the silence of mute spectators, those who stand against oppression, those who are busy in perfecting themselves first, all matters which we reveal and which we conceal, to everything He is The Witness!
He is Al-Adl and Ash- Shaheed,
The Most Just One is Himself The Witness of everything, everything!
So neither despair nor grieve seeing the oppressors given the respite.
The Most Just is The Witness of every affair and He is The Ultimate Judge.
May He witness us among those with whom He is well pleased.
