"Allah, may He be blessed and exalted, says: 'Fasting is for me and I shall reward for it. The fasting person has two moments of joy: When he breaks his fast and when he meets his Lord.' By the One in whose hand is my soul, the smell that comes from the mouth of the fasting person is better before Allah than the fragrance of musk." ' (Using translation from Nasāʾī 2211)
عَنْ رَسُولِ اللهِ ﷺ قَالَ إِنَّ اللهَ يَقُولُ الصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ وَلِلصَّائِمِ فَرْحَتَانِ حِينَ يُفْطِرُ وَحِينَ يَلْقَى رَبَّهُ وَالَّذِي نَفْسِي بِيَدِهِ لَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ
