البيهقي:٨٣٩٨وَأَخْبَرَنَا أَبُو مُحَمَّدٍ عَبْدُ اللهِ بْنُ يَحْيَى بْنِ عَبْدِ الْجَبَّارِ السُّكَّرِيُّ بِبَغْدَادَ أنبأ إِسْمَاعِيلُ بْنُ مُحَمَّدٍ الصَّفَّارُ ثنا أَحْمَدُ بْنُ مَنْصُورٍ ثنا عَبْدُ الرَّزَّاقِ أنبأ ابْنُ جُرَيْجٍ عَنْ عُبَيْدِ اللهِ بْنِ أَبِي يَزِيدَ

أَنَّهُ سَمِعَ ابْنَ عَبَّاسٍ يَقُولُ مَا رَأَيْتُ رَسُولَ اللهِ ﷺ يَتَحَرَّى صِيَامَ يَوْمٍ يَلْتَمِسُ فَضْلَهُ عَلَى غَيْرِهِ إِلَّا هَذَا الْيَوْمَ يَوْمَ عَاشُورَاءَ وَشَهْرَ رَمَضَانَ  

رَوَاهُ مُسْلِمٌ فِي الصَّحِيحِ عَنْ مُحَمَّدِ بْنِ رَافِعٍ عَنْ عَبْدِ الرَّزَّاقِ وَأَخْرَجَاهُ مِنْ حَدِيثِ ابْنِ عُيَيْنَةَ عَنْ عُبَيْدِ اللهِ
