"(Allah says) fasting is for me and I shall reward for it. The fasting person rejoices twice: when he breaks his fast and the day when he meets his Lord. And the smell that come from the mouth of the fasting person is better before Allah than the fragrance of musk." ' (Using translation from Nasāʾī 2214)
عَنْ رَسُولِ اللهِ ﷺ قَالَ قَالَ اللهُ الصِّيَامُ لِي وَأَنَا أَجْزِي بِهِ وَالصَّائِمُ يُفْرَحُ مَرَّتَيْنِ عِنْدَ فِطْرِهِ وَيَوْمَ يَلْقَى اللهَ وَلَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ
