Hadith 1139
وحَدَّثَنَا
أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا
وَكِيعٌ ، عَنِ
ابْنِ عَوْنٍ ، عَنْ
زِيَادِ بْنِ جُبَيْرٍ ، قَالَ : جَاءَ رَجُلٌ إِلَى ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا ، فَقَالَ : إِنِّي نَذَرْتُ أَنْ أَصُومَ يَوْمًا ، فَوَافَقَ يَوْمَ أَضْحَى أَوْ فِطْرٍ ، فَقَالَ
ابْنُ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا : " أَمَرَ اللَّهُ تَعَالَى بِوَفَاءِ النَّذْرِ ، وَنَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ صَوْمِ هَذَا الْيَوْمِ " . .
Ziyad bin Jubair reported that a person came to Ibn 'Umar (RA) and said: 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 (RA) 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.
