Hadith 8129

وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ ، لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ مِنْ رِيحِ الْمِسْكِ ، يَذَرُ شَهْوَتَهُ وَطَعَامَهُ وَشَرَابَهُ مِنْ جَرَّايَ ، فَالصِّيَامُ لِي وَأَنَا أَجْزِي بِهِ " .
And the Prophet Muhammad (peace be upon him) said: By Him in Whose hand is the soul of Muhammad (peace be upon him), the breath of the fasting person is more pleasant to Allah than the fragrance of musk. The fasting person leaves his food, drink, and desires for My sake; therefore, fasting is for Me, and I Myself will reward for it.
