حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، عَنْ سُفْيَانَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَابِسٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، حَدَّثَنِي رَجُلٌ، مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الْحِجَامَةِ وَالْمُوَاصَلَةِ وَلَمْ يُحَرِّمْهُمَا إِبْقَاءً عَلَى أَصْحَابِهِ فَقِيلَ لَهُ يَا رَسُولَ اللَّهِ إِنَّكَ تُوَاصِلُ إِلَى السَّحَرِ . فَقَالَ " إِنِّي أُوَاصِلُ إِلَى السَّحَرِ وَرَبِّي يُطْعِمُنِي وَيَسْقِينِي " .
Narrated 'Abd al-Rahman b. Abi Laila: A man from the Companions of the Prophet (PBUH) told me that the Messenger of Allah (PBUH) prohibited cupping and perpetual fasting, but he had not made them unlawful showing mercy on his Companions. Thereupon he was asked: Messenger of Allah, you observe perpetual fast till dawn. He replied: I observe perpetual fast till dawn (for) my Lord gives me food and drink. Translation Not Available
