Narrated Sahl:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ ، قَالَ حَدَّثَنَا ابْنُ أَبِي حَازِمٍ ، عَنْ أَبِيهِ ، عَنْ سَهْلٍ ، بِهَذَا وَقَالَ مَا كُنَّا نَقِيلُ وَلاَ نَتَغَدَّى إِلاَّ بَعْدَ الْجُمُعَةِ.
As above with the addition: We never had an afternoon nap nor meals except after offering the Jumua prayer.
