The Prophet ﷺ said, "Allah said: The Fast is for Me and I will give the reward for it, as he (the one who observes the fast) leaves his sexual desire, food and drink for My Sake. Fasting is a screen (from Hell) and there are two pleasures for a fasting person, one at the time of breaking his fast, and the other at the time when he will meet his Lord. And the smell of the mouth of a fasting person is better in Allah's Sight than the smell of musk." (See Hadith No. 128, Vol. 3). (Using translation from Bukhārī 7492)
قَالَ رَسُولُ اللهِ ﷺ يَقُولُ اللهُ الصَّوْمُ لِي وَأَنَا أَجْزِي بِهِ يَدَعُ شَهْوَتَهُ وَأَكْلَهُ وَشُرْبَهُ مِنْ أَجْلِي وَالصَّوْمُ جُنَّةٌ وَلِلصَّائِمِ فَرْحَتَانِ فَرْحَةٌ حِينَ يُفْطِرُ وَفَرْحَةٌ حِينَ يَلْقَى اللهَ وَلَخُلُوفُ فِيهِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ
