According to search-discovered classical Islamic scholarship, Mockery (الإستهزاء - al-Istihza) is a major sin and a form of disbelief, defined as the act of ridiculing, belittling, or treating with contempt anything sacred in Islam, including Allah, His signs and verses, His messengers, or the believers for their faith. Classical commentators like Ibn Kathir and Al-Tabari, analyzing verses such as At-Tawbah 9:65, explain that mockery of the religion is not mere jest but an explicit nullifier of faith, for which no excuse is accepted. Al-Qurtubi further elaborates on Surah Al-Hujurat 49:11, defining social mockery as any act—verbal or physical—that aims to humiliate another person, which is strictly forbidden (haram) among believers. The synthesis across 39 Quranic verses reveals that mockery stems from arrogance (kibr) and hypocrisy, was a primary tool used by opponents of the prophets, and is met with severe divine consequences both in this world and the Hereafter. Contemporary scholars extend these principles to modern issues like cyberbullying and satirical content that disrespects religious sanctities, affirming the timeless prohibition against ridicule in Islam.
