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}
Abd al-Aziz ibn Abdullah narrated to us; Sulayman ibn Bilal narrated to us, from Humayd, from Anas, who said: The Messenger of Allah ﷺ abstained from approaching his wives by an oath. His leg had been injured, and he stayed in an upper room for twenty-nine nights. Then he came down, and they said: O Messenger of Allah, you swore to stay away for a month. He said: A month can be twenty-nine days.
