حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا مُحَمَّدُ بْنُ زِیَادٍ، قَالَ سَمِعْتُ أَبَا هُرَیْرَةَ، عَنِ النَّبِیِّ صلى الله علیه وسلم یَرْوِیهِ عَنْ رَبِّكُمْ، قَالَ ‏ "‏ لِكُلِّ عَمَلٍ كَفَّارَةٌ، وَالصَّوْمُ لِی وَأَنَا أَجْزِی بِهِ، وَلَخَلُوفُ فَمِ الصَّائِمِ أَطْیَبُ عِنْدَ اللَّهِ مِنْ رِیحِ الْمِسْكِ ‏"‏‏.‏

Narrated Abu Huraira:

The Prophet said that your Lord said, "Every (sinful) deed can be expiated; and the fast is for Me, so I will give the reward for it; and the smell which comes out of the mouth of a fasting person, is better in Allah's Sight than the smell of musk."
