Indeed, those who came with falsehood1 are a group among you. Do not think it bad for you; rather, it is good for you. For every person among them is what [punishment] he has earned from the sin, and he who took upon himself the greater portion thereof2 - for him is a great punishment [i.e., Hellfire].
Translation: Saheeh International (English)
1 Referring to the incident when the Prophet's wife ʿĀ’ishah was falsely accused by the hypocrites.
2 i.e., ʿAbdullāh bin ʿUbayy, leader of the hypocrites.

Tafsir
Those that brought the slander (which was accusing the Mother of the Believers Aishah - may Allah be pleased with her - of adultery) are a group which affiliate themselves to you, O believers. Do not consider the slander they made as bad for you, but rather it is good, due to the reward and testing of the believers it contains, and due to the clearing the name of the Mother of the Believers it brings with it. For each person who shared in accusing her of adultery is the reward of the sin he earned, due to uttering the slander. And for the one who bore the majority of that by starting it is a great punishment. The one meant by that is the leader of the hypocrites, Abdullah ibn Ubayy ibn Salool.
