حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ حَدَّثَنَا عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَاصَلَ فِي رَمَضَانَ فَوَاصَلَ النَّاسُ فَنَهَاهُمْ فَقِيلَ لَهُ إِنَّكَ تُوَاصِلُ قَالَ إِنِّي لَسْتُ مِثْلَكُمْ إِنِّي أُطْعَمُ وَأُسْقَى
مسند امام احمد بن حنبل · Hadith 5795
It was narrated from Ibn 'Umar that the Messenger of Allah (PBUH) fasted continuously (without breaking the fast at night) in Ramadan, so the people fasted continuously. Then he forbade them to do that. It was said to him: But you fast continuously. He said: "I am not like one of you; I am fed and given to drink (by my Lord)."
