Tafsir
The aforementioned, i.e. those who migrated in the path of Allah being entered into paradise, and permission for the wronged to avenge justly without incurring sin. If the oppressor returns to his oppression, Allah will help the oppressed. Indeed, Allah overlooks the sins of the believers and forgives them.
