Hadith #1

عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ عَلِيِّ بْنِ حَسَّانَ عَنْ مُوسَى بْنِ بَكْرٍ قَالَ اشْتَكَى غُلَامٌ لِأَبِي الْحَسَنِ ( عليه السلام ) فَسَأَلَ عَنْهُ فَقِيلَ بِهِ طُحَالٌ فَقَالَ أَطْعِمُوهُ الْكُرَّاثَ ثَلَاثَةَ أَيَّامٍ فَأَطْعَمْنَاهُ فَقَعَدَ الدَّمُ ثُمَّ بَرَأَ .

1. A number of our people have narrated from Sahl ibn Ziyad from Ali ibn Hassan from Musa ibn Bakr who has said the following: “Once, a slave of abu al-Hassan complained of illness. He (the Imam) asked about him and it was said that he has spleen trouble. He (the Imam) said, Teed him leeks for three days.’ We fed him, blood formed and he became well.’”
