حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا سُلَيْمَانُ بْنُ بِلَالٍ ، عَنْ حُمَيْدٍ ، عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ ، قَالَ : " آلَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ نِسَائِهِ ، وَكَانَتِ انْفَكَّتْ رِجْلُهُ ، فَأَقَامَ فِي مَشْرُبَةٍ تِسْعًا وَعِشْرِينَ لَيْلَةً ، ثُمَّ نَزَلَ ، فَقَالُوا : يَا رَسُولَ اللَّهِ ، آلَيْتَ شَهْرًا ؟ فَقَالَ : إِنَّ الشَّهْرَ يَكُونُ تِسْعًا وَعِشْرِينَ " .
Narrated Anas: Allah's Apostle vowed to keep aloof from his wives for one month, and he had dislocation of his leg. So, he stayed in a Mashruba for 29 nights and then came down. Some people said, "O Allah's Apostle! You vowed to stay aloof for one month," He replied, "The month is of 29 days."
