حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ ح وَحَدَّثَنَا ابْنُ نُمَيْرٍ حَدَّثَنَا أَبِى حَدَّثَنَا عُثْمَانُ بْنُ حَكِيمٍ الأَنْصَارِىُّ قَالَ سَأَلْتُ سَعِيدَ بْنَ جُبَيْرٍ عَنْ صَوْمِ رَجَبٍ - وَنَحْنُ يَوْمَئِذٍ فِى رَجَبٍ - فَقَالَ سَمِعْتُ ابْنَ عَبَّاسٍ - رضى الله عنهما - يَقُولُ كَانَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- يَصُومُ حَتَّى نَقُولَ لاَ يُفْطِرُ. وَيُفْطِرُ حَتَّى نَقُولَ لاَ يَصُومُ.

Uthman bin Hakim Al-Ansari said:”I asked Sa’eed bin jubair about fasting in Rajab, as we were in Rajab at the time, and he said: ‘I heard Ibn ‘Abbas [may Allah be pleased with them] say: “The Messenger of Allah (SAW) used to fast until we would say: ‘He will not stop fasting,’ and he would stop fasting until we would say: ‘He will not fast.’”
