Sahih Bukhari Volume 9, Book 96, Hadith 7301

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا هِشَامٌ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ لاَ تُوَاصِلُوا ‏"‏‏.‏ قَالُوا إِنَّكَ تُوَاصِلُ‏.‏ قَالَ ‏"‏ إِنِّي لَسْتُ مِثْلَكُمْ، إِنِّي أَبِيتُ يُطْعِمُنِي رَبِّي وَيَسْقِينِي ‏"‏‏.‏ فَلَمْ يَنْتَهُوا عَنِ الْوِصَالِ ـ قَالَ ـ فَوَاصَلَ بِهِمُ النَّبِيُّ صلى الله عليه وسلم يَوْمَيْنِ أَوْ لَيْلَتَيْنِ، ثُمَّ رَأَوُا الْهِلاَلَ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ لَوْ تَأَخَّرَ الْهِلاَلُ لَزِدْتُكُمْ ‏"‏‏.‏ كَالْمُنَكِّي لَهُمْ‏

Narrated By Abu Huraira : The Prophet said (to his companions), "Do not fast Al-Wisal." They said, "But you fast Al-Wisail." He said, "I am not like you, for at night my Lord feeds me and makes me drink." But the people did not give up Al-Wisal, so the Prophet fasted Al-Wisal with them for two days or two nights, and then they saw the crescent whereupon the Prophet said, "If the crescent had delayed, I would have continued fasting (because of you)," as if he wanted to vanquish them completely (because they had refused to give up Al Wisal).
