The superiority of As-Saum (the fasting)

Narrated Abu Huraira:

Allah's Apostle ﷺ said, "Fasting is a shield (or a screen or a shelter). So, the person observing fasting should avoid sexual relation with his wife and should not behave foolishly and impudently, and if somebody fights with him or abuses him, he should tell him twice, 'I am fasting." The Prophet added, "By Him in Whose Hands my soul is, the smell coming out from the mouth of a fasting person is better in the sight of Allah than the smell of musk. (Allah says about the fasting person), 'He has left his food, drink and desires for My sake. The fast is for Me. So I will reward (the fasting person) for it and the reward of good deeds is multiplied ten times."

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " الصِّيَامُ جُنَّةٌ، فَلاَ يَرْفُثْ وَلاَ يَجْهَلْ، وَإِنِ امْرُؤٌ قَاتَلَهُ أَوْ شَاتَمَهُ فَلْيَقُلْ إِنِّي صَائِمٌ. مَرَّتَيْنِ، وَالَّذِي نَفْسِي بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ تَعَالَى مِنْ رِيحِ الْمِسْكِ، يَتْرُكُ طَعَامَهُ وَشَرَابَهُ وَشَهْوَتَهُ مِنْ أَجْلِي، الصِّيَامُ لِي، وَأَنَا أَجْزِي بِهِ، وَالْحَسَنَةُ بِعَشْرِ أَمْثَالِهَا ".
