وَعَنِ ابْنِ عَبَّاسٍ
قَالَ: مَا رَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَحَرَّى صِيَامَ يَوْمٍ فَضَّلَهُ عَلَى غَيْرِهِ إِلَّا هَذَا الْيَوْمَ: يَوْمَ عَاشُورَاءَ وَهَذَا الشَّهْرُ يَعْنِي شَهْرَ رَمَضَان
“I never saw the Prophet (sallallahu alayhi wa sallam) singling out any day’s fast and considering it more excellent than another, except this day, the day of Ashura,* and this month, meaning the month of Ramadan.” *The 10th of Muharram.
