Ash-Shama'il Al-Muhammadiyah, Book 26, Hadith 178 (In-Book)

Hazrat Salma radiyallahu anha says that Hazrat Hasan, Hazrat Abdullah ibn Abbas and Hazrat Abdullah ibn Ja'far Sadiq radiyallahu anhum came to her and said, Cook for us the food that Rasoolullah sallallahu alaihe wasallam liked and ate with pleasure. She replied, O my children, you will not like it now. (It was only liked in times of hardships.) They replied, Of course, we will surely like it. She got up and took a bit of barley, (crushed it) and put it in a pot, and poured a little olive oil over it, then crushed some chillies and spices and added it to the pot and served it, saying, This is what Rasoolullah sallallahu alaihe wasallam loved (and ate with pleasure).

حَدَّثَنَا الْحُسَيْنُ بْنُ مُحَمَّدٍ الْبَصْرِيُّ، قَالَ‏:‏ حَدَّثَنَا الْفُضَيْلُ بْنُ سُلَيْمَانَ، قَالَ‏:‏ حَدَّثَنِي فَائِدٌ، مَوْلَى عُبَيْدِ اللهِ بْنِ عَلِيِّ بْنِ أَبِي رَافِعٍ مَوْلَى رَسُولِ اللهِ صلى الله عليه وسلم، قَالَ‏:‏ حَدَّثَنِي عُبَيْدُ اللهِ بْنُ عَلِيٍّ، عَنْ جَدَّتِهِ سَلْمَى، أَنَّ الْحَسَنَ بْنَ عَلِيٍّ، وَابْنَ عَبَّاسٍ، وَابْنَ جَعْفَرٍ أَتَوْهَا فَقَالُوا لَهَا‏:‏ اصْنَعِي لَنَا طَعَامًا مِمَّا كَانَ يُعْجِبُ رَسُولَ اللهِ صلى الله عليه وسلم، وَيُحْسِنُ أَكْلَهُ فَقَالَتْ‏:‏ يَا بُنَيَّ لا تَشْتَهِيهِ الْيَوْمَ، قَالَ‏:‏ بَلَى اصْنَعِيهِ لَنَا قَالَ‏:‏ فَقَامَتْ فَأَخَذَتْ مِنْ شَعِيرٍ فَطَحَنَتْهُ، ثُمَّ جَعَلَتْهُ فِي قِدْرٍ، وَصَبَّتْ عَلَيْهِ شَيْئًا مِنْ زَيْتٍ، وَدَقَّتِ الْفُلْفُلَ، وَالتَّوَابِلَ، فَقَرَّبَتْهُ إِلَيْهِمْ، فَقَالَتْ‏:‏ هَذَا مِمَّا كَانَ يُعْجِبُ رَسُولَ اللهِ صلى الله عليه وسلم، وَيُحْسِنُ أَكْلَهُ‏.‏
