قَالَ حَدَّثَنَا حَجَّاجٌ قَالَ حَدَّثَنَا لَيْثُ بْنُ سَعْدٍ قَالَ حَدَّثَنِي يَزِيدُ بْنُ أَبِي حَبِيبٍ عَنْ سَعِيدِ بْنِ أَبِي هِنْدٍ أَنَّ مُطَرِّفًا مِنْ بَنِي عَامِرِ بْنِ صَعْصَعَةَ حَدَّثَهُ أَنَّ عُثْمَانَ بْنَ أَبِي الْعَاصِ الثَّقَفِيَّ دَعَا لَهُ بِلَبَنٍ لِيَسْقِيَهُ فَقَالَ مُطَرِّفٌ إِنِّي صَائِمٌ فَقَالَ عُثْمَانُ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ الصِّيَامُ جُنَّةٌ مِنْ النَّارِ كَجُنَّةِ أَحَدِكُمْ مِنْ الْقِتَالِ وَسَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ صِيَامٌ حَسَنٌ صِيَامُ ثَلَاثَةِ أَيَّامٍ مِنْ الشَّهْرِ.
English Translation
He said: Hajjaj told us: Layth ibn Sa'd told us: Yazid ibn Abi Habib told me, from Sa'id ibn Abi Hind, that Mutarrif, from Banu 'Amir ibn Sa'sa'ah, told him that 'Uthman ibn Abi al-'As al-Thaqafi called for milk to be brought to give him to drink, and Mutarrif said: I am fasting. 'Uthman said: I heard the Messenger of Allah, peace and blessings be upon him, say: Fasting is a shield from the Fire like the shield of one of you in battle, and I heard the Messenger of Allah, peace and blessings be upon him, say: A good fast is the fasting of three days each month.
