The Prophet ﷺ said, "(Allah said), 'Every good deed of Adam's son is for him except fasting; it is for Me. and I shall reward (the fasting person) for it.' Verily, the smell of the mouth of a fasting person is better to Allah than the smell of musk."

عَنِ النَّبِيِّ ﷺ قَالَ كُلُّ عَمَلِ ابْنِ آدَمَ لَهُ إِلاَّ الصَّوْمَ فَإِنَّهُ لِي وَأَنَا أَجْزِي بِهِ وَلَخَلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ مِنْ رِيحِ الْمِسْكِ

Messenger of Allah 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 ﷺ 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."

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۔»

Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "By the One in Whose hand my self is, the smell of the breath of a man fasting is better with Allah than the scent of musk.' He leaves his desires and his food and drink for My sake. Fasting is for Me and I reward it. Every good action is rewarded by ten times its kind, up to seven hundred times, except fasting, which is for Me, and I reward it.' "

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ مِنْ رِيحِ الْمِسْكِ إِنَّمَا يَذَرُ شَهْوَتَهُ وَطَعَامَهُ وَشَرَابَهُ مِنْ أَجْلِي فَالصِّيَامُ لِي وَأَنَا أَجْزِي بِهِ كُلُّ حَسَنَةٍ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِمِائَةِ ضِعْفٍ إِلاَّ الصِّيَامَ فَهُوَ لِي وَأَنَا أَجْزِي بِهِ

[Machine] And the Messenger of Allah ﷺ said, "By the One in whose hand is the soul of Muhammad, the breath of the fasting person is sweeter to Allah than the fragrance of musk. The fasting person abstains from their desires, food, and drink for My sake, and I will reward them for it."

وَقَالَ رَسُولُ اللهِ ﷺ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ يَذَرُ شَهْوَتَهُ وَطَعَامَهُ وَشَرَابَهُ مِنْ جَرَّايَ فَالصِّيَامُ لِي وَأَنَا أَجْزِي بِهِ

[Machine] The Messenger of Allah ﷺ said, "A good deed is multiplied by ten of its like, and fasting is for Me and I alone will reward it. A person leaves his food and drink for My sake, so fasting is for Me and I alone will reward it. The odor of the mouth of a fasting person is more pleasant to Allah than the scent of musk."

أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْحَسَنَةُ بِعَشْرِ أَمْثَالِهَا وَالصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ إِنَّهُ يَذَرُ طَعَامَهُ وَشَرَابَهُ مِنْ أَجْلِي فَالصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ وَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ

[Machine] "Indeed, the Messenger of Allah ﷺ said: By the One in Whose hand is my soul, the smell from the mouth of a fasting person is more pleasant to Allah than the scent of musk. He leaves his food, drink, and desires for My sake. The fasting is for Me and I will reward it. Every good deed is rewarded ten times its like, up to seven hundred times, except for fasting, as it is for Me and I will reward it."

إِنَّ رَسُولَ اللهِ ﷺ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ يَذَرُ طَعَامَهُ وَشَرَابَهُ وَشَهْوَتَهُ مِنْ أَجْلِي فَالصِّيَامُ لِي وَأَنَا أَجْزِي بِهِ كُلُّ حَسَنَةٍ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِ مِائَةِ ضِعْفٍ إِلَّا الصِّيَامَ فَهُوَ لِي وَأَنَا أَجْزِي بِهِ

[Machine] The Messenger of Allah ﷺ said, "By the One in whose hand is my soul, the scent of the fasting person's mouth is more pleasant to Allah than the scent of musk. He says, 'The fasting person abstains from their desires, food, and drink for My sake. Fasting is for Me and I will reward it accordingly, with every good deed being multiplied ten times to seven hundred times, except for fasting, which is for Me and I will reward it.'"

أَنَّ رَسُولَ اللهِ ﷺ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ يَقُولُ ﷻ إِنَّمَا يَذَرُ شَهْوَتَهُ وَطَعَامَهُ وَشَرَابَهُ مِنْ أَجْلِي فَالصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ كُلُّ حَسَنَةٍ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِ مِائَةِ ضِعْفٍ إِلَّا الصِّيَامَ فَهُوَ لِي وَأَنَا أَجْزِي بِهِ

[Machine] From the Prophet ﷺ who said, "A good deed is worth ten like it and fasting is for Me and I will reward it. The person observing fasting leaves his desires and food and drink for My sake. Fasting is for Me and I will reward it. The odor in the mouth of a fasting person is better in the sight of Allah than the fragrance of musk."

عَنِ النَّبِيِّ ﷺ قَالَ الْحَسَنَةُ بِعَشْرِ أَمْثَالِهَا وَالصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ يَذَرُ طَعَامَهُ وَشَرَابَهُ بِجَرَّايَ قَالَ يَزِيدُ مِنْ أَجْلِي الصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ وَلَخُلُوفُ فَمِ الصَّائِمِ عِنْدَ اللهِ أَطْيَبُ مِنْ رِيحِ الْمِسْكِ

The Prophet ﷺ said, "(Allah said), 'Every good deed of Adam's son is for him except fasting; it is for Me. and I shall reward (the fasting person) for it.' Verily, the smell of the mouth of a fasting person is better to Allah than the smell of musk." (Using translation from Bukhārī 5927)

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ «كُلُّ عَمَلِ ابْنِ آدَمَ لَهُ إِلَّا الصِّيَامَ وَالصِّيَامُ لِي وَأَنَا أَجْزِي بِهِ وَلَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ مِنْ رِيحِ الْمِسْكِ»

[Machine] "Indeed, the Messenger of Allah ﷺ said, 'By the One in whose hand is my soul, the smell of the mouth of a fasting person is more beloved to Allah than the scent of musk. Allah says, 'The fasting person abandons their desires, food, and drink for My sake. Fasting is for Me and I will reward it accordingly. Every good deed is rewarded ten times its value, up to seven hundred times, except for fasting, for it is for Me and I will reward it.'"

أَنَّ رَسُولَ اللهِ ﷺ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ يَقُولُ اللهُ ﷻ إِنَّمَا يَتْرُكُ شَهْوَتَهُ وَطَعَامَهُ وَشَرَابَهُ مِنْ أَجْلِي وَالصِّيَامُ لِي وَأَنَا أَجْزِي بِهِ كُلُّ حَسَنَةٍ بِعَشْرَةِ أَمْثَالِهَا إِلَى سَبْعِمِائَةِ ضِعْفٍ إِلَّا الصِّيَامَ فَهُوَ لِي وَأَنَا أَجْزِي بِهِ

"قَال رَبُّكْمُ: الصَّوْمُ جُنَّةٌ مِنَ النَّارِ، وَلِى الصَّوْمُ وَأنَا أجْزِى به يَدَعُ شَهْوَتَه وَطَعَامَهُ وَشَرَابَهُ مِنْ أجْلِى، لَخَلُوفُ فمِ الصائِم أطيَبُ عنْدَ اللهِ مِن ريح الْمِسْكِ".

"كُلُّ عَمَلِ ابْنِ آدَمَ لَه إلا الصِّيامَ، وَالصِّيامُ (* *) لي وَأَنَا أَجزى به، وَلَخُلُوفُ فَم الصَّائِم أطيَبُ عِنْدَ الله مِن رِيح الْمِسْكِ".
