Dar Al-Ifta received a question regarding the ruling on praying against a neighbor who harms others with offensive speech and foul language, and someone praying for illness, such as cancer, upon them. The authority clarified that the harmful person’s actions are sinful, while a Muslim should respond to harm with good and pray for their guidance. The Quran emphasizes: ﴿Repel evil with what is better; then the one between whom and you there was enmity [will become] as though he was a devoted friend﴾ [41:34].

Praying harm or illness upon a fellow Muslim is not permitted, as it constitutes harm, contrary to the Prophet’s saying: “Do not harm and do not reciprocate harm” (Malik). Recommended ways to address harm include:

Responding with good conduct and kindness, countering evil with good.

Praying for the wrongdoer’s guidance and repentance.

Resorting to legal action if the person persists in harmful behavior.

Dar Al-Ifta also emphasized the importance of maintaining good neighborly relations, citing the Prophet’s saying: “Gabriel continued to advise me regarding the neighbor until I thought he would inherit from him,” highlighting the significance of patience, good manners, and ethical conduct when facing offenses.
