Is it permissible to supplicate against someone for them to become completely paralyzed if they intend to harm the supplicant?

The prayer of the oppressed against their oppressor is permissible with its Sharia (definition)-compliant stipulations, but forgiveness is more virtuous. Your prayer for the woman to be completely paralyzed is not permissible because she has not harmed you yet. If she does harm you, then praying against her is permissible only to the extent of the injustice. We advise you to fortify yourself with the prescribed remembrances (adhkar) and supplications (du'as) to repel evils, such as: "O Allah, suffice me against them however You wish," and "O Allah, we place You in their throats and seek refuge in You from their evils."
