Narrated by 'Abdur-Rahman bin Al-Aswad
(On the authority of his father) 'Aisha said: "Whenever Allah's Apostle wanted to fondle anyone of us during her periods (menses), he used to order her to put on an Izar and start fondling her." 'Aisha added, "None of you could control his sexual desires as the Prophet could."
