أَخْبَرَنَا الرَّبِيعُ بْنُ سُلَيْمَانَ بْنِ دَاوُدَ، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي مَالِكٌ، وَعَمْرُو بْنُ الْحَارِثِ، وَذَكَرَ، آخَرَ قَبْلَهُمَا أَنَّ أَبَا النَّضْرِ، حَدَّثَهُمْ عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصُومُ حَتَّى نَقُولَ مَا يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ مَا يَصُومُ وَمَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي شَهْرٍ أَكْثَرَ صِيَامًا مِنْهُ فِي شَعْبَانَ .
It was narrated that 'Aishah said:"The Messenger of Allah used to fast until we said: 'He will not break his fast.' And he used not to fast until we said: 'He will not fast.' And I never saw the Messenger of Allah fast more in any month than in Shaban
Usamah bin Zaid said:"I said: 'O Messenger of Allah, I do not see you fasting any month as much as Shaban.' He said: 'That is a month to which people do not pay much attention, between Rajab and Ramadan. It is a month in which the deeds are taken up to the Lord of the worlds, and I like that my deeds be taken up when I am fasting
Usamah bin Zaid said:"I said: 'O Messenger of Allah, sometimes you fast, and you hardly ever break your hardly ever fast, except two days which, if you are fasting, you include them in your fast, and if you are not fasting, then you fast them on your own.' He said: 'Which two days?' I said: 'Monday and Thursday.' He said: 'Those are two days in which deeds are shown to the Lord of the worlds, and I like my deeds to be shown (to Him) when I am fasting
It was narrated from Usamah bin Zaid:That the Messenger of Allah used to fast continually and it ws said that he would not break his fast, and he used not to fast and it was said that he would not fast
