Hasan al-Basri (may Allah have mercy on him) said: "When the Messenger of Allah (peace and blessings be upon him) came to Makkah for ‘Umrah, the women of Madinah came adorned. The Companions complained, so the Prophet (peace and blessings be upon him) said: 'Benefit from them and fix a period of three days, and I think that whoever stays with a woman for three days will also have relations with her from the back.'"
