AHMAD 26683: from Ibn Jurayj —
[Machine] The Prophet ﷺ swore not to visit some of his family for a month. However, when twenty-nine days passed, he either came or left. It was said to him, "O Prophet of Allah, did you not swear not to visit them for a month?" He replied, "Indeed, the month consists of twenty-nine days."

أحمد ٢٦٦٨٣: عن ابن جريج —
أَنَّ النَّبِيَّ ﷺ حَلَفَ أَنْ لَا يَدْخُلَ عَلَى بَعْضِ أَهْلِهِ شَهْرًا فَلَمَّا مَضَى تِسْعَةٌ وَعِشْرُونَ يَوْمًا غَدَا عَلَيْهِمْ أَوْ رَاحَ فَقِيلَ لَهُ حَلَفْتَ يَا نَبِيَّ اللهِ لَا تَدْخُلُ عَلَيْهِمْ شَهْرًا؟ فَقَالَ إِنَّ الشَّهْرَ تِسْعَةٌ وَعِشْرُونَ يَوْمًا
