Messenger of Allah ﷺ took an oath that he would not go to his wives for one month as his foot had been sprained. He stayed in an upper room when ʿUmar went to him and said, "Have you divorced your wives?" He said, "No, but I have taken an oath that I would not go to them for one month." The Prophet stayed there for twenty-nine days, and then came down and went to his wives.
آلَى رَسُولُ اللَّهِ ﷺ مِنْ نِسَائِهِ شَهْرًا وَكَانَتِ انْفَكَّتْ قَدَمُهُ فَجَلَسَ فِي عِلِّيَّةٍ لَهُ فَجَاءَ عُمَرُ فَقَالَ أَطَلَّقْتَ نِسَاءَكَ قَالَ لاَ وَلَكِنِّي آلَيْتُ مِنْهُنَّ شَهْرًا فَمَكُثَ تِسْعًا وَعِشْرِينَ ثُمَّ نَزَلَ فَدَخَلَ عَلَى نِسَائِهِ
