[Machine] We were with the Prophet ﷺ one day, and a drink was brought to him. He drank from it and then gave it to the people, who also drank from it. The container then passed by a man from the people, and he said, "I am fasting." Some of the people said that it doesn't break the fast, as he fasts every day. The Prophet ﷺ said, "Neither fasting nor breaking the fast is for one who fasts forever."  

الطبراني:٢٠٩١٨حَدَّثَنَا عُبَيْدُ بْنُ غَنَّامٍ ثنا أَبُو بَكْرِ بْنِ أَبِي شَيْبَةَ ثنا الْمُحَارِبِيُّ ح وَحَدَّثَنَا الْحُسَيْنُ بْنُ إِسْحَاقَ التُّسْتَرِيُّ ثنا عُثْمَانُ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا جَرِيرٌ كِلَاهُمَا عَنْ لَيْثٍ عَنْ شَهْرِ بْنِ حَوْشَبٍ عَنْ أَسْمَاءَ بِنْتِ يَزِيدَ قَالَتْ

كُنَّا عِنْدَ النَّبِيِّ ﷺ ذَاتَ يَوْمٍ فَأُتِيَ بِشَرَابٍ فَشَرِبَ ثُمَّ أَعْطَى الْقَوْمَ فَشَرِبُوا فَمَرَّ الْإِنَاءُ عَلَى رَجُلٍ مِنَ الْقَوْمِ فَقَالَ «إِنِّي صَائِمٌ» فَقَالَ بَعْضُ الْقَوْمِ إِنَّهُ لَا يُفْطِرُ إِنَّهُ يَصُومُ كُلَّ يَوْمٍ فَقَالَ النَّبِيُّ ﷺ «لَا صَامَ وَلَا أَفْطَرَ مَنْ صَامَ الْأَبَدَ»
