As we have already mentioned we BELIEVE that God is JUST and He never oppresses; because cruel acts are indecent and unbecoming to Him:_
.....And thy LORD will treat no one with injustice.
If some people are punished in this world or in the Hereafters, it is due to their own deeds:_
It is not God who oppresses them, but they wrong their own soul.
Not only Man, but rather no creature in the world is ever oppressed by God:_
Allah wants no injustice to any of His creatures.
All these verses are some how a guidance towards making use of our wisdom.
