Sahih al-Bukhari, Hadith 7241 ⓘ
Narrated Anas: The Prophet fasted Al-Wisal on the last days of the month. Some people did the same, and when the news reached the Prophet he said, "If the month had been prolonged for me, then I would have fasted Wisal for such a long time that the most exaggerating ones among you would have given up their exaggeration. I am not like you; my Lord always makes me eat and drink."
حَدَّثَنَا عَيَّاشُ بْنُ الْوَلِيدِ، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا حُمَيْدٌ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، رضى الله عنه قَالَ وَاصَلَ النَّبِيُّ صلى الله عليه وسلم آخِرَ الشَّهْرِ، وَوَاصَلَ أُنَاسٌ، مِنَ النَّاسِ فَبَلَغَ النَّبِيَّ صلى الله عليه وسلم فَقَالَ " لَوْ مُدَّ بِيَ الشَّهْرُ لَوَاصَلْتُ وِصَالاً يَدَعُ الْمُتَعَمِّقُونَ تَعَمُّقَهُمْ، إِنِّي لَسْتُ مِثْلَكُمْ، إِنِّي أَظَلُّ يُطْعِمُنِي رَبِّي وَيَسْقِينِ " . تَابَعَهُ سُلَيْمَانُ بْنُ مُغِيرَةَ عَنْ ثَابِتٍ عَنْ أَنَسٍ عَنِ النَّبِيِّ صلى الله عليه وسلم.
