سنن ابن ماجه#1639Sahihحَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ الْمِصْرِيُّ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ سَعِيدِ بْنِ أَبِي هِنْدٍ، أَنَّ مُطَرِّفًا، مِنْ بَنِي عَامِرِ بْنِ صَعْصَعَةَ حَدَّثَهُ أَنَّ عُثْمَانَ بْنَ أَبِي الْعَاصِ الثَّقَفِيَّ دَعَا لَهُ بِلَبَنٍ يَسْقِيهِ فَقَالَ مُطَرِّفٌ: إِنِّي صَائِمٌ . فَقَالَ عُثْمَانُ: سَمِعْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ: " الصِّيَامُ جُنَّةٌ مِنَ النَّارِ كَجُنَّةِ أَحَدِكُمْ مِنَ الْقِتَالِ " .
Mutarrif, from the tribe of Banu ‘Amir bin Sa’sa’ah narrated that ‘Uthman bin Abul-‘As Ath-Thaqafi invited him to drink some milk that he poured for him. Mutarrif said:“I am fasting.” ‘Uthman said: “I heard the Messenger of Allah (ﷺ) say: ‘Fasting is a shield against the Fire just like the shield of anyone of you against fighting.’”
