حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِی أَبِی، عَنْ قَتَادَةَ، قَالَ حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، قَالَ كَانَ النَّبِیُّ صلى الله علیه وسلم یَدُورُ عَلَى نِسَائِهِ فِی السَّاعَةِ الْوَاحِدَةِ مِنَ اللَّیْلِ وَالنَّهَارِ، وَهُنَّ إِحْدَى عَشْرَةَ‏.‏ قَالَ قُلْتُ لأَنَسٍ أَوَكَانَ یُطِیقُهُ قَالَ كُنَّا نَتَحَدَّثُ أَنَّهُ أُعْطِیَ قُوَّةَ ثَلاَثِینَ‏.‏
وَقَالَ سَعِیدٌ عَنْ قَتَادَةَ إِنَّ أَنَسًا حَدَّثَهُمْ تِسْعُ نِسْوَةٍ‏.‏

Narrated Qatada:

Anas bin Malik said, "The Prophet used to visit all his wives in a round, during the day and night and they were eleven in number." I asked Anas, "Had the Prophet the strength for it?" Anas replied, "We used to say that the Prophet was given the strength of thirty (men)." And Sa`id said on the authority of Qatada that Anas had told him about nine wives only (not eleven).
