أَخْبَرَنَا
قُتَيْبَةُ ، قَالَ : حَدَّثَنَا
سُفْيَانُ ، عَنْ
عُبَيْدِ اللَّهِ ، أَنَّهُ سَمِعَ
ابْنَ عَبَّاسٍ ، وَسُئِلَ عَنْ صِيَامِ عَاشُورَاءَ ، قَالَ : " مَا عَلِمْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَامَ يَوْمًا يَتَحَرَّى فَضْلَهُ عَلَى الْأَيَّامِ ، إِلَّا هَذَا الْيَوْمَ ، يَعْنِي شَهْرَ رَمَضَانَ وَيَوْمَ عَاشُورَاءَ " .
´It was narrated from 'Ubaidullah that:` he heard Ibn 'Abbas, when he was asked about the fast of 'Ashura' say: "I do not know that the Prophet fasted any day because of its virtue, except this day" meaning the month of Ramadan and the day of Ashura.'
