Sahih Bukhari Volume 3, Book 41, Hadith 2350

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ ـ رضى الله عنه ـ أَنَّهُ قَالَ إِنَّا كُنَّا نَفْرَحُ بِيَوْمِ الْجُمُعَةِ، كَانَتْ لَنَا عَجُوزٌ تَأْخُذُ مِنْ أُصُولِ سِلْقٍ لَنَا كُنَّا نَغْرِسُهُ فِي أَرْبِعَائِنَا فَتَجْعَلُهُ فِي قِدْرٍ لَهَا فَتَجْعَلُ فِيهِ حَبَّاتٍ مِنْ شَعِيرٍ لاَ أَعْلَمُ إِلاَّ أَنَّهُ قَالَ لَيْسَ فِيهِ شَحْمٌ وَلاَ وَدَكٌ، فَإِذَا صَلَّيْنَا الْجُمُعَةَ زُرْنَاهَا فَقَرَّبَتْهُ، إِلَيْنَا فَكُنَّا نَفْرَحُ بِيَوْمِ الْجُمُعَةِ مِنْ أَجْلِ ذَلِكَ وَمَا كُنَّا نَتَغَدَّى وَلاَ نَقِيلُ إِلاَّ بَعْدَ الْجُمُعَةَ‏.‏

Narrated By Sahl bin Sad : We used to be very happy on Friday as an old lady used to cut some roots of the Silq, which we used to plant on the banks of our small water streams, and cook them in a pot of hers, adding to them, some grains of barley. (Ya'qub, the sub-narrator said, "I think the narrator mentioned that the food did not contain fat or melted fat (taken from meat).") When we offered the Friday prayer we would go to her and she would serve us with the dish. So, we used to be happy on Fridays because of that. We used not to take our meals or the midday nap except after the Jumua prayer (i.e. Friday prayer).
