What was narrated concerning the virtues of fasting

It was narrated from Abu Hurairah that the Messenger of Allah ﷺ said:
“Every good deed of the son of Adam will be multiplied manifold. A good deed will be multiplied ten times up to as many as seven hundred times, or as much as Allah wills. Allah says: ‘Except for fasting, which is for Me and I shall reward for it. He gives up his desire and his food for My sake.’ The fasting person has two joys, one when he breaks his fast and another when he meets his Lord. The smell that comes from the mouth of a fasting person is better before Allah than the fragrance of musk.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، وَوَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " كُلُّ عَمَلِ ابْنِ آدَمَ يُضَاعَفُ الْحَسَنَةُ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِمِائَةِ ضِعْفٍ إِلَى مَا شَاءَ اللَّهُ يَقُولُ اللَّهُ إِلاَّ الصَّوْمَ فَإِنَّهُ لِي وَأَنَا أَجْزِي بِهِ يَدَعُ شَهْوَتَهُ وَطَعَامَهُ مِنْ أَجْلِي لِلصَّائِمِ فَرْحَتَانِ فَرْحَةٌ عِنْدَ فِطْرِهِ وَفَرْحَةٌ عِنْدَ لِقَاءِ رَبِّهِ وَلَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ مِنْ رِيحِ الْمِسْكِ " .

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.’”

حَدَّثَنَا 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 ﷺ يَقُولُ " الصِّيَامُ جُنَّةٌ مِنَ النَّارِ كَجُنَّةِ أَحَدِكُمْ مِنَ الْقِتَالِ " .
