Narrated Abu Huraira:
حَدَّثَنَا يَحْيَى ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ ، عَنْ مَعْمَرٍ ، عَنْ هَمَّامٍ ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِيَّاكُمْ وَالْوِصَالَ ". مَرَّتَيْنِ قِيلَ إِنَّكَ تُوَاصِلُ. قَالَ " إِنِّي أَبِيتُ يُطْعِمُنِي رَبِّي وَيَسْقِينِ، فَاكْلَفُوا مِنَ الْعَمَلِ مَا تُطِيقُونَ ".
The Prophet (ﷺ) said twice, "(O you people) Be cautious! Do not practice Al-Wisal." The people said to him, "But you practice Al-Wisal?" The Prophet (ﷺ) replied, "My Lord gives me food and drink during my sleep. Do that much of deeds which is within your ability."
