What is the ruling on a person saying to another, "May the curse of Hubal be upon you," or "May the gods curse you," whether in jest or seriously? Does this count as major disbelief (kufr) and shirk (associating partners with Allah) that expels its perpetrator from Islam and nullifies his deeds? And what must he do to return to Islam if that is the case?

These phrases are abhorrent and reprehensible, and they may lead their utterer to disbelief (kufr) or sin. If the intention behind them is merely to narrate the words of disbelievers, it is a grave sin but does not constitute disbelief. However, if the intention is to affirm deities alongside Allah the Almighty, even in jest, this is disbelief that expels one from the faith, based on the words of Allah the Almighty: "And if you ask them, they will surely say, 'We were only indulging in idle talk and amusement.' Say, 'Is it in Allah and His verses and His Messenger that you were mocking?' Make no excuses; you have disbelieved after your belief." The one who utters this must repent to Allah, pronounce the two testimonies of faith (Shahadatain), and feel remorse.
