21- The Different Types of Oppression and the Type Which Will not be Forgiven
1927- “Oppression is of three types, the oppression which Allaah will not leave, an oppression that will be forgiven, and an oppression that will not be forgiven.
As for the oppression which will not be forgiven, then Shirk will not be forgiven.
As for the oppression which will be forgiven, then that is the oppression which the slave commits between himself and his Lord.
As for the oppression which will not be left, then it is the oppression of the slaves, then Allaah will take the rights some from others.”
