Sayyidah Aishah (may Allah be pleased with her) said: When Allah Almighty revealed my innocence in the incident of the Ifk (slander), the Prophet (peace and blessings be upon him) ordered concerning two men and a woman that the prescribed punishment for slander (qadhf) be applied to them. Those who had made the accusation were: Abdullah bin Ubayy, Mistah bin Uthathah (may Allah be pleased with him), Hassan bin Thabit (may Allah be pleased with him), and Hamnah bint Jahsh (may Allah be pleased with her), the sister of Zaynab bint Jahsh (may Allah be pleased with her); they had accused Sayyidah Aishah (may Allah be pleased with her) with Safwan bin al-Mu'attal al-Sulami (may Allah be pleased with him).
