وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم 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 ‏"‏ ‏.‏

Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, 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
