Hadith 11:63
Narrated Sahl:
As above with the addition: We never had an afternoon nap nor meals except after offering the Jumua prayer.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، قَالَ حَدَّثَنَا ابْنُ أَبِي حَازِمٍ، عَنْ أَبِيهِ، عَنْ سَهْلٍ، بِهَذَا وَقَالَ مَا كُنَّا نَقِيلُ وَلاَ نَتَغَدَّى إِلاَّ بَعْدَ الْجُمُعَةِ
