[Machine] The Messenger of Allah used to visit his wives day and night, and they were eleven in number. I asked Anas, "Could he afford to have relations with all of them?" Anas replied, "We used to say that he was given the strength of thirty men." This is the wording of the hadith of Muhammad ibn Abi Bakr, and its meaning is also mentioned in the hadith of Ibn Bashshar. In another narration by Ibn Al-Muthanna, it states the strength of forty men. Anas also said, "He [the Prophet] used to visit his wives during the day and night."  

كَانَ رَسُولُ اللهِ ﷺ يَدُورُ عَلَى نِسَائِهِ مِنَ اللَّيْلِ وَالنَّهَارِ فِي السَّاعَةِ وَهُنَّ إِحْدَى عَشْرَةَ قُلْتُ لِأَنَسٍ هَلْ كَانَ يُطِيقُ ذَلِكَ؟ قَالَ كُنَّا نَتَحَدَّثُ أَنَّهُ أُعْطِيَ قُوَّةَ ثَلَاثِينَ هَذَا لَفْظُ حَدِيثِ مُحَمَّدِ بْنِ أَبِي بَكْرٍ وَبِمَعْنَاهُ حَدِيثُ ابْنِ بَشَّارٍ وَفِي رِوَايَةِ ابْنِ الْمُثَنَّى قُوَّةُ أَرْبَعِينَ وَقَالَ عَنْ أَنَسٍ ؓ وَقَالَ فِي السَّاعَةِ مِنَ اللَّيْلِ وَالنَّهَارِ
