Sahih Bukhari Volume 7, Book 70, Hadith 5405

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا يَعْقُوبُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ، قَالَ إِنْ كُنَّا لَنَفْرَحُ بِيَوْمِ الْجُمُعَةِ، كَانَتْ لَنَا عَجُوزٌ تَأْخُذُ أُصُولَ السِّلْقِ، فَتَجْعَلُهُ فِي قِدْرٍ لَهَا، فَتَجْعَلُ فِيهِ حَبَّاتٍ مِنْ شَعِيرٍ، إِذَا صَلَّيْنَا زُرْنَاهَا فَقَرَّبَتْهُ إِلَيْنَا، وَكُنَّا نَفْرَحُ بِيَوْمِ الْجُمُعَةِ مِنْ أَجْلِ ذَلِكَ، وَمَا كُنَّا نَتَغَدَّى وَلاَ نَقِيلُ إِلاَّ بَعْدَ الْجُمُعَةِ، وَاللَّهِ مَا فِيهِ شَحْمٌ وَلاَ وَدَكٌ‏.‏

Narrated By Sahl bin Sad : We used to be happy on Fridays, for there was an old lady who used to pull out the roots of Silq and put it in a cooking pot with some barley. When we had finished the prayer, we would visit her and she would present that dish before us. So we used to be happy on Fridays because of that, and we never used to take our meals or have a mid-day nap except after the Friday prayer. By Allah, that meal contained no fat.
