وَعَنْهُ أَيْضًا عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَتْ: أَرْبَعٌ لَمْ يَكُنْ يَدَعُهُنَّ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ صِيَامَ عَاشُورَاءَ وَالْعَشْرَ وَثَلَاثَةَ أَيَّامٍ مِنْ كُلِّ شَهْرٍ وَرَكْعَتَيْنِ قَبْلَ الْغَدَاةِ
Narrated from Sayyida Hafsa (may Allah be pleased with her), she said that the Messenger of Allah (peace and blessings be upon him) never abandoned four practices: fasting on the day of Ashura, fasting during the ten days of Dhul-Hijjah, fasting three days of every month, and performing the two Sunnah units before the Fajr prayer.
