Mukhtasar Bukhari

´Sayyiduna Anas (may Allah be pleased with him) says that` the Prophet Muhammad (peace and blessings be upon him) used to visit all his (wives) within a single hour of the night or day, and they were eleven. In another narration, it is mentioned that there were nine women. So Anas (may Allah be pleased with him) was asked, "Did the Prophet (peace and blessings be upon him) have the strength for all of them?" He replied, "(Yes, rather)" we used to say among ourselves that the Prophet (peace and blessings be upon him) was given the strength of thirty men.
