وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنِ ابْنِ عَوْنٍ، عَنْ زِيَادِ بْنِ جُبَيْرٍ، قَالَ جَاءَ رَجُلٌ إِلَى ابْنِ عُمَرَ - رضى الله عنهما - فَقَالَ إِنِّي نَذَرْتُ أَنْ أَصُومَ يَوْمًا فَوَافَقَ يَوْمَ أَضْحَى أَوْ فِطْرٍ ‏.‏ فَقَالَ ابْنُ عُمَرَ رضى الله عنهما أَمَرَ اللَّهُ تَعَالَى بِوَفَاءِ النَّذْرِ وَنَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ صَوْمِ هَذَا الْيَوْمِ ‏.‏

I had taken a vow that I would fast on the day (but it accidentally) synchronises with the day of Adha or the day of Fitr. Thereupon Ibn ‘Umar (Allah be pleased with him) said: Allah, the Exalted, has commanded fulfilling of the vow, but the Messenger of Allah (ﷺ) has forbidden the observance of fast on this day.
