مُوَطَّأُ مَالِكٍ
Muwatta Malik 672
Fasting
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الْوِصَالِ فَقَالُوا يَا رَسُولَ اللَّهِ فَإِنَّكَ تُوَاصِلُ فَقَالَ إِنِّي لَسْتُ كَهَيْئَتِكُمْ إِنِّي أُطْعَمُ وَأُسْقَى .
Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, (ﷺ), forbade fasting for two days or more without breaking the fast in between. They said, "But Messenger of Allah, you practise wisal." He replied, "I am not the same as you. I am fed and given to drink."
