“Every good deed of the son of Adam will be multiplied manifold. A good deed will be multiplied ten times up to as many as seven hundred times, or as much as Allah wills. Allah says: ‘Except for fasting, which is for Me and I shall reward for it. He gives up his desire and his food for My sake.’ The fasting person has two joys, one when he breaks his fast and another when he meets his Lord. The smell that comes from the mouth of a fasting person is better before Allah than the fragrance of musk.” (Using translation from Ibn Mājah 1638)
قَالَ رَسُولُ اللهِ ﷺ كُلُّ عَمَلِ ابْنِ آدَمَ يُضَاعَفُ الْحَسَنَةُ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِ مِائَةِ ضِعْفٍ إِلَى مَا شَاءَ اللهُ قَالَ اللهُ ﷻ إِلَّا الصَّوْمَ فَإِنَّهُ لِي وَأَنَا أَجْزِي بِهِ يَدَعُ طَعَامَهُ وَشَهْوَتَهُ مِنْ أَجْلِي لِلصَّائِمِ فَرْحَتَانِ فَرْحَةٌ عِنْدَ فِطْرِهِ وَفَرْحَةٌ عِنْدَ لِقَاءِ رَبِّهِ وَلَخُلُوفُ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللهِ مِنْ رِيحِ الْمِسْكِ الصَّوْمُ جُنَّةٌ الصَّوْمُ جُنَّةٌ
