عَنْ عُثْمَانَ بْنِ حَكِيمٍ قَالَ: سَأَلْتُ سَعِيدَ بْنَ جُبَيْرٍ عَنْ صَوْمِ رَجَبٍ كَيْفَ تَرَى فِيهِ؟ قَالَ: حَدَّثَنِي ابْنُ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ يَصُومُ حَتَّى نَقُولَ لَا يُفْطِرُ، وَيُفْطِرُ حَتَّى نَقُولَ لَا يَصُومُ
‘Uthman bin Hakim says: I asked Sa‘id bin Jubayr about fasting in the month of Rajab, what is his opinion about it? He said: Sayyiduna ‘Abdullah bin ‘Abbas (may Allah be pleased with him) narrated to me that the Messenger of Allah (peace and blessings be upon him) would sometimes begin to fast so frequently that we would think he would not leave off fasting at all, but then he (peace and blessings be upon him) would leave off fasting for such a long period that we would think he would never fast again.
