Oaths and Vows
Whoever took an oath that he would not enter upon his wife for one month
حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُلَيْمَانُ بْنُ بِلاَلٍ، عَنْ حُمَيْدٍ، عَنْ أَنَسٍ، قَالَ آلَى رَسُولُ اللَّهِ صلى الله عليه وسلم 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 Messenger (ﷺ) took an oath for abstention from his wives (for one month), and during those days he had a sprain in his foot. He stayed in a Mashrubah (an upper room) for twenty-nine nights and then came down. Then the people said, "O Allah's Messenger (ﷺ) ! You took an oath for abstention (from your wives) for one month." On that he said, "A (lunar) month can be of twenty-nine days."
