Arabic (Original)
حَدَّثَنَا أَبُو كَامِلٍ قَالَ حَدَّثَنَا حَمَّادٌ يَعْنِي ابْنَ سَلَمَةَ عَنْ عَاصِمِ بْنِ بَهْدَلَةَ عَنْ سَوَاءٍ الْخُزَاعِيِّ عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَصُومُ ثَلَاثَةَ أَيَّامٍ مِنْ كُلِّ شَهْرٍ يَوْمَ الِاثْنَيْنِ وَيَوْمَ الْخَمِيسِ وَيَوْمَ الِاثْنَيْنِ مِنْ الْجُمُعَةِ الْأُخْرَى.
English Translation
Abu Kamil told us, he said Hammad - meaning Ibn Salamah - told us, from 'Asim b. Bahdalah, from Sawa' al-Khuza'i, from Hafsah, wife of the Prophet (peace and blessings be upon him), that the Prophet (peace and blessings be upon him) used to fast three days of every month: Monday, Thursday, and the Monday of the following week.
