وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " كُلُّ عَمَلِ ابْنِ آدَمَ يُضَاعَفُ الْحَسَنَةُ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِمِائَةِ ضِعْفٍ قَالَ اللَّهُ تَعَالَى: إِلَّا الصَّوْمَ فَإِنَّهُ لِي وَأَنَا أَجْزِي بِهِ يَدَعُ شَهْوَتَهُ وَطَعَامَهُ مِنْ أَجْلِي لِلصَّائِمِ فَرْحَتَانِ: فَرْحَةٌ عِنْدَ فِطْرِهِ وَفَرْحَةٌ عِنْدَ لِقَاءِ رَبِّهِ وَلَخُلُوفِ فَمِ الصَّائِمِ أَطْيَبُ عِنْدَ اللَّهِ مِنْ رِيحِ الْمِسْكِ وَالصِّيَامُ جُنَّةٌ وَإِذَا كَانَ يَوْمُ صَوْمِ أَحَدِكُمْ فَلَا يَرْفُثْ وَلَا يصخب وفإن سَابَّهُ أَحَدٌ أَوْ قَاتَلَهُ فَلْيَقُلْ إِنِّي امْرُؤٌ صَائِم "
English Translation
He reported God’s messenger as saying, "Every and when the day of the fast of any of you comes he must not use vile language or raise his voice, and if anyone reviles him or tries to fight with him he should tell him he is fasting.” *This is not from the Qur’an, but is a hadith qudsi, a tradition which gives words spoken by God. (Bukhari and Muslim.)
