1. Dying unrepentant in shirk: its non-forgiveness is established by revelation.
2. Other sins: forgiveness remains possible by divine will, including for major offenses.
3. Warnings: they establish real moral danger and potential punishment, without making eternal punishment inescapable for every non-shirk sinner.
4. Minor sins: their lesser rank does not make them lawful; punishment and expiation must be understood according to their conditions.
5. Repentance: turning away from sin, regretting it, and reform remain obligatory; possible pardon gives no reason to abandon them.
This preserves divine justice, truthful revelation, the seriousness of warning, and the breadth of mercy without conflating their functions.
