Sayyiduna Anas bin Malik (may Allah be pleased with him) states: The Prophet (peace and blessings be upon him) passed by some people in Makkah. They began to mock him behind his back and to say: This is the one who claims that he is a prophet. Sayyiduna Jibril (peace be upon him) was with the Prophet (peace and blessings be upon him). He jabbed a man with his finger (or pointed at him), and something like a boil appeared on their bodies; it turned into sores, until their bodies began to stink, and no one could go near them. Then Allah Almighty revealed this verse: "Indeed, We are sufficient for you against the mockers."
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and al-Bazzar recorded something similar. Its chain contains a narrator, Yazid bin Dirham, whom Yahya bin Ma'in declared da'if (weak), while al-Fallas declared him thiqah (trustworthy).
