Arabic (Original)
حَدَّثَنَا أَبُو النَّضْرِ وَحَسَنُ بْنُ مُوسَى قَالَا ثَنَا شَيْبَانُ عَنْ لَيْثٍ عَنْ شَهْرٍ عَنْ أَسْمَاءَ بِنْتِ يَزِيدَ قَالَتْ أُتِيَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِشَرَابٍ فَدَارَ عَلَى الْقَوْمِ وَفِيهِمْ رَجُلٌ صَائِمٌ فَلَمَّا بَلَغَهُ قَالَ لَهُ اشْرَبْ فَقِيلَ يَا رَسُولَ اللَّهِ إِنَّهُ لَيْسَ يُفْطِرُ وَيَصُومُ الدَّهْرَ فَقَالَ يَعْنِي رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا صَامَ مَنْ صَامَ الْأَبَدَ.
English Translation
Abu al-Nadr and Hasan ibn Musa narrated to us. They said: Shayban narrated to us, from Layth, from Shahr, from Asma' bint Yazid, who said: A drink was brought to the Prophet (peace and blessings of Allah be upon him) and was passed around the people. Among them was a fasting man. When it reached him, the Prophet said to him: "Drink." It was said: "O Messenger of Allah, he does not break his fast; he fasts perpetually." The Messenger of Allah (peace and blessings of Allah be upon him) said: "The one who fasts perpetually has not truly fasted."
