Narrated `Abdullah bin `Umar:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، أَخْبَرَنَا مَالِكٌ ، عَنْ نَافِعٍ ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الْوِصَالِ. قَالُوا إِنَّكَ تُوَاصِلُ. قَالَ " إِنِّي لَسْتُ مِثْلَكُمْ، إِنِّي أُطْعَمُ وَأُسْقَى ".
Allah's Messenger (ﷺ) forbade Al-Wisal. The people said (to him), "But you practice it?" He said, "I am not like you, for I am given food and drink by Allah."
