Arabic (Original)
وَبِإِسْنَادِهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ عَزَّ وَجَلَّ مِنْ رِيحِ الْمِسْكِ يَقُولُ إِنَّمَا يَذَرُ شَهْوَتَهُ وَطَعَامَهُ وَشَرَابَهُ مِنْ أَجْلِي فَالصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ مِنْ كُلِّ حَسَنَةٍ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِ مِائَةِ ضِعْفٍ إِلَّا الصِّيَامَ فَهُوَ لِي وَأَنَا أَجْزِي بِهِ.
English Translation
And with his chain of transmission: the Messenger of Allah, peace and blessings be upon him, said: "By the One in whose hand is my soul, the breath odor of the fasting person's mouth is more pleasant to Allah, Mighty and Sublime, than the scent of musk. He leaves his desire, his food, and his drink for My sake; fasting is for Me, and I reward for it. Every good deed is rewarded ten times its like up to seven hundred times, except fasting, for it is for Me, and I reward for it."
