Ash-Shama'il Al-Muhammadiyah, Book 25, Hadith 172 (English)

Hazrat Umme Munzir radiyallahu anha says, Rasoolullah sallallahu alaihe wasallam visited me. Hazrat Ali radiyallahu anhu was with him. We had some bunches of dates hanging. Rasoolullah sallallahu alaihe wasallam began eating from them. Hazrat Ali radiyallahu anhu also began eating with him. Rasoolullah sallallahu alaihe wasallam stopped him saying, "You have just recovered from your illness and should not eat this." He (Ali radiyallahu anhu) stopped and Rasoolullah sallallahu alaihe wasallam continued eating. Hazrat Umme Munzir radiyallahu anha says, I then cooked some barley and beetroot. Rasoolullah sallallahu alaihe wasallam said to Hazrat Ali radiyallahu anhu, "Eat this, it is suitable for you."

حَدَّثَنَا الْعَبَّاسُ بْنُ مُحَمَّدٍ الدُّورِيُّ، قَالَ‏:‏ حَدَّثَنَا يُونُسُ بْنُ مُحَمَّدٍ، قَالَ‏:‏ حَدَّثَنَا فُلَيْحُ بْنُ سُلَيْمَانَ، عَنْ عُثْمَانَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ يَعْقُوبَ بْنِ أَبِي يَعْقُوبَ، عَنْ أُمِّ الْمُنْذِرِ، قَالَتْ‏:‏ دَخَلَ عَلَيَّ رَسُولُ اللهِ صلى الله عليه وسلم، وَمَعَهُ عَلِيٌّ، وَلَنَا دَوَالٍ مُعَلَّقَةٌ، قَالَتْ‏:‏ فَجَعَلَ رَسُولُ اللهِ صلى الله عليه وسلم يَأْكُلُ وَعَلِيٌّ مَعَهُ يَأْكُلُ، فَقَالَ رَسُولُ اللهِ صلى الله عليه وسلم، لِعَلِيٍّ‏:‏ مَهْ يَا عَلِيُّ، فَإِنَّكَ نَاقَةٌ، قَالَتْ‏:‏ فَجَلَسَ عَلِيٌّ، وَالنَّبِيُّ صلى الله عليه وسلم يَأْكُلُ، قَالَتْ‏:‏ فَجَعَلْتُ لَهُمْ سِلْقًا وَشَعِيرًا، فَقَالَ النَّبِيُّ صلى الله عليه وسلم لِعَلِيٍّ‏:‏ مِنْ هَذَا فَأَصِبْ فَإِنَّ هَذَا أَوْفَقُ لَكَ‏.‏
