Narrated Abu Huraira:

Allah's Apostle forbade Al-Wisal. The people said (to him), "But you fast Al-'Wisal," He said, "Who among you is like me? When I sleep (at night), my Lord makes me eat and drink. But when the people refused to give up Al-Wisal, he fasted Al-Wisal along with them for two days and then they saw the crescent whereupon the Prophet ﷺ said, "If the crescent had not appeared I would have fasted for a longer period," as if he intended to punish them herewith.

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، وَقَالَ اللَّيْثُ، حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ خَالِدٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ سَعِيدَ بْنَ الْمُسَيَّبِ، أَخْبَرَهُ أَنَّ أَبَا هُرَيْرَةَ قَالَ نَهَى رَسُولُ اللَّهِ ﷺ عَنِ الْوِصَالِ، قَالُوا فَإِنَّكَ تُوَاصِلُ. قَالَ " أَيُّكُمْ مِثْلِي، إِنِّي أَبِيتُ يُطْعِمُنِي رَبِّي وَيَسْقِينِ ". فَلَمَّا أَبَوْا أَنْ يَنْتَهُوا وَاصَلَ بِهِمْ يَوْمًا ثُمَّ يَوْمًا ثُمَّ رَأَوُا الْهِلاَلَ فَقَالَ " لَوْ تَأَخَّرَ لَزِدْتُكُمْ ". كَالْمُنَكِّلِ لَهُمْ.
