The Prophet ﷺ 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 ﷺ fasted Al-Wisal with them for two days or two nights, and then they saw the crescent whereupon the Prophet ﷺ 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). (Using translation from Bukhārī 7299)
عَنِ النَّبِيِّ ﷺ قَالَ «لَا تُوَاصِلُوا» قَالُوا يَا رَسُولَ اللَّهِ إِنَّكَ تُوَاصِلُ فَقَالَ «إِنِّي لَسْتُ مِثْلَكُمْ إِنِّي أَبِيتُ يُطْعِمُنِي رَبِّي وَيَسْقِينِي» فَلَمْ يَنْتَهُوا عَنِ الْوِصَالِ فَوَاصَلَ بِهِمُ النَّبِيُّ ﷺ يَوْمَيْنِ وَلَيْلَتَيْنِ ثُمَّ رَأَوَا الْهِلَالَ فَقَالَ رَسُولُ اللَّهِ ﷺ «لَوْ تَأَخَّرَ الْهِلَالُ لَزِدْتُكُمْ» كَالْمُنَكِّلِ لَهُمْ
