The Book of Fasting
The Difference Between our fasting and the Fasting of the people of the Book
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ مُوسَى بْنِ عُلَىٍّ، عَنْ أَبِيهِ، عَنْ أَبِي قَيْسٍ، عَنْ عَمْرِو بْنِ الْعَاصِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِنَّ فَصْلَ مَا بَيْنَ صِيَامِنَا وَصِيَامِ أَهْلِ الْكِتَابِ أَكْلَةُ السُّحُورِ .
It was narrated that 'Amr bin Al-As said: "The Messenger of Allah said: 'The difference between our fasting and the fasting of the people of the Book, is eating Sahur."' '
