- It is prohibited to respond to harm with more than its equivalent.
- Allah did not enjoin upon His servants anything harmful to them.
- It is prohibited to cause or reciprocate harm with words, deeds, or lack of action.
- Recompense is of the same type as the deed. So, whoever causes harm, Allah harms him, and whoever makes things difficult, Allah makes things difficult for him.
- One of the Sha‘i rules is that "harm should be removed", for the Shariah disapproves of harming and condemns harming.
