1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from abu Yahya al-Wasitiy from a man who has said the following: “Abu ‘ Abd Allah , has said,

’Eating clay is unlawful in its entirety, like the flesh of pork. If one eats it and dies, I will not perform Salat (prayer) for him except the clay from the grave (of al-Husayn ) in which there is cure for all kinds of illnesses but if one eats it because of strong desire, then there is no cure in it.’”
