Al-Husayn b. Ahmad b. Idris narrated to us. He said: My father narrated to us from Ahmad b. Muhammad b. `Isa from `Ali b. al-Hakam from Isma`il al-Munqari from his grandfather Ziyad b. Abi Ziyad from Abi Ja`far Muhammad b. `Ali al-Baqir . He said:

Whoever eats clay will find his body itching, he will have hemorrhoids, a bad malady will irritate him, he will lose power in his legs and feet, and his health will deteriorate so much that his work will decrease, difficulty will consume him, and he will suffer.
