وَعَنْ حَفْصَةَ
قَالَتْ: أَرْبَعٌ لَمْ يَكُنْ يَدَعُهُنَّ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «صِيَامُ عَاشُورَاءَ وَالْعَشْرِ وَثَلَاثَةُ أَيَّامٍ مِنْ كُلِّ شَهْرٍ وَرَكْعَتَانِ قبل الْفجْر»
fasting on Ashura, the first ten days of Dhul Hijja* and three days every month, and praying two rakas before dawn. *The Arabic has simply ‘the ten’, to be understood as translated above. Nasai transmitted it.
