BUKHARI 7538:
from Abū Hurayrah —
[Machine] From the Prophet ﷺ, narrating from your Lord, He said: “For every deed there is an expiation; fasting is for Me, and I will reward for it. And the odor from the mouth of the fasting person is more pleasing to Allah than the fragrance of musk.”
البخاري ٧٥٣٨:
عن ابو هريره —
عَنِ النَّبِيِّ ﷺ يَرْوِيهِ عَنْ رَبِّكُمْ قَالَ: «لِكُلِّ عَمَلٍ كَفَّارَةٌ وَالصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ وَلَخَلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ مِنْ رِيحِ الْمِسْكِ».
