Abu Huraira reported: The Messenger of Allah, peace be upon him, said: Allah Almighty said, “All the deeds of the children of Adam are for them, except fasting which is for Me, and I will give the reward for it.” The Messenger of Allah said further, “Fasting is a shield. If one of you is fasting, he should avoid sexual relations with his wife and arguments. If somebody should fight or argue with him, he should say: I am fasting. By Him in Whose Hand is my soul, the unpleasant smell coming from the mouth of a fasting person is better in the sight of Allah than the smell of musk. There are two pleasures for the fasting person, one at the time of breaking his fast and the other when he meets his Lord; then he will be pleased because of his fasting.”
[Sahih Muslim, Book 6, Number 2566]
أَبَا هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ يَقُولُ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ
اللَّهُ عَزَّ وَجَلَّ كُلُّ عَمَلِ ابْنِ آدَمَ لَهُ إِلَّا الصِّيَامَ
فَإِنَّهُ لِي وَأَنَا أَجْزِي بِهِ وَالصِّيَامُ جُنَّةٌ فَإِذَا كَانَ
يَوْمُ صَوْمِ أَحَدِكُمْ فَلَا يَرْفُثْ يَوْمَئِذٍ وَلَا يَسْخَبْ فَإِنْ
سَابَّهُ أَحَدٌ أَوْ قَاتَلَهُ فَلْيَقُلْ إِنِّي امْرُؤٌ صَائِمٌ
وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ
عِنْدَ اللَّهِ يَوْمَ الْقِيَامَةِ مِنْ رِيحِ الْمِسْكِ وَلِلصَّائِمِ
فَرْحَتَانِ يَفْرَحُهُمَا إِذَا أَفْطَرَ فَرِحَ بِفِطْرِهِ وَإِذَا
لَقِيَ رَبَّهُ فَرِحَ بِصَوْمِهِ
صحيح مسلم كِتَاب الصِّيَامِ الصيام جنة
