Messenger of Allah ﷺ forbade Al-Wisal (fasting continuously for more than one day without taking any meals). A man from the Muslims said, "But you do Al-Wisal, O Messenger of Allah ﷺ!" Messenger of Allah ﷺ I said, "Who among you is similar to me? I sleep and my Lord makes me eat and drink." When the people refused to give up Al-Wisal, the Prophet ﷺ fasted along with them for one day, and did not break his fast but continued his fast for another day, and when they saw the crescent, the Prophet ﷺ said, "If the crescent had not appeared, I would have made you continue your fast (for a third day)," as if he wanted to punish them for they had refused to give up Al-Wisal.
نَهَى رَسُولُ اللَّهِ ﷺ عَنِ الْوِصَالِ فَقَالَ لَهُ رِجَالٌ مِنَ الْمُسْلِمِينَ فَإِنَّكَ يَا رَسُولَ اللَّهِ تُوَاصِلُ فَقَالَ رَسُولُ اللَّهِ ﷺ أَيُّكُمْ مِثْلِي إِنِّي أَبِيتُ يُطْعِمُنِي رَبِّي وَيَسْقِينِ فَلَمَّا أَبَوْا أَنْ يَنْتَهُوا عَنِ الْوِصَالِ وَاصَلَ بِهِمْ يَوْمًا ثُمَّ يَوْمًا ثُمَّ رَأَوُا الْهِلاَلَ فَقَالَ لَوْ تَأَخَّرَ لَزِدْتُكُمْ كَالْمُنَكِّلِ بِهِمْ حِينَ أَبَوْا
