Anas bin Malik reported,

The Prophet of Allah ﷺ used to visit all of his wives in a single night, and at that time he had nine wives.In another narration, the Prophet ﷺ used to go around to all of his wives in a single hour of the night or day, and they were eleven.The narrator said, I asked Anas, "Was he able to do that?"He replied, "We used to say that he was given the strength of thirty men."

عن أنس بن مالك قال

إن نبي الله ﷺ كان يطوف على نسائه في الليلة الواحدة، وله يومئذ تسع نسوة. وفي رواية: كان النبي ﷺ يدور على نسائه في الساعة الواحدة من الليل والنهار وهن إحدى عشرة قال: قلت لأنس: أو كان يطيقه؟ قال: كنا نتحدث أنه أعطي قوة ثلاثين.
