Atiyyah al-Awfi narrated from Ibn Abbas (may Allah be pleased with them both) concerning this verse: "Indeed, those who accuse chaste, unaware, believing women are cursed in this world and the Hereafter, and for them is a great punishment" [Surah al-Nur: 23]: that is, the wives of the Prophet (peace and blessings be upon him), whom the hypocrites targeted with slander; so Allah made curse and wrath binding upon them (the hypocrites), and they incurred the wrath of Allah. All of this is about the wives of the Prophet (peace and blessings be upon him).
