حَدَّثَنَا الْحُسَيْنُ بْنُ إِسْمَاعِيلَ الْمَحَامِلِيُّ ، ثنا خَلادُ بْنُ أَسْلَمَ ، ثنا هُشَيْمٌ ، عَنْ يُونُسَ بْنِ عُبَيْدٍ ، عَنِ ابْنِ جُبَيْرٍ وَهُوَ زِيَادُ بْنُ جُبَيْرِ بْنِ حَيَّةَ ، قَالَ : رَأَيْتُ رَجُلا جَاءَ إِلَى ابْنِ عُمَرَ فَسَأَلَهُ ، فَقَالَ : إِنَّهُ نَذَرَ أَنْ يَصُومَ كُلَّ يَوْمِ أَرْبِعَاءَ فَأَتَى ذَلِكَ عَلَى يَوْمِ فِطْرٍ أَوْ أَضْحًى ، فَقَالَ ابْنُ عُمَرَ : " أَمَرَ اللَّهُ بِوَفَاءِ النَّذْرِ ، وَنَهَانَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ صَوْمِ يَوْمِ النَّحْرِ " . إِسْنَادٌ صَحِيحٌ.
Ziyad bin Jubair narrates: I remember, a man came to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) and asked him that he had made a vow to fast every Wednesday, but this day coincided with the day of Eid al-Fitr and Eid al-Adha, so what should he do now? Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) replied: "Allah Almighty has commanded the fulfillment of vows, and the Noble Prophet (peace and blessings be upon him) has forbidden us from fasting on the days of sacrifice." Its chain of narration is authentic.
