حَدَّثَنَا سُفْيَانُ قَالَ أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ أَبِي يَزِيدَ مُنْذُ سَبْعِينَ سَنَةً قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ يَقُولُ مَا عَلِمْتُ رَسُولَ اللَّهِ ص
َلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَامَ يَوْمًا يَتَحَرَّى فَضْلَهُ عَلَى الْأَيَّامِ غَيْرَ يَوْمِ عَاشُورَاءَ وَقَالَ سُفْيَانُ مَرَّةً أُخْرَى إِلَّا هَذَا الْيَوْمَ يَعْنِي عَاشُورَاءَ وَهَذَا الشَّهْرَ شَهْرَ رَمَضَانَ

English Translation
Sufyan narrated to us, he said: 'Ubaydullah ibn Abi Yazid informed me seventy years ago. He said: I heard Ibn 'Abbas say: "I did not know the Messenger of Allah ﷺ to deliberately fast any day seeking its merit over other days except the day of 'Ashura'." Sufyan said on another occasion: "except this day, meaning 'Ashura', and this month, meaning the month of Ramadan."
