13.52.1

Wonders are displayed by this group. Among them: one of them will remain for months without eating or drinking. For many of them pits are dug under the ground and built over, leaving only an opening through which air enters, and he stays there for months; I heard that some of them stay thus for a year! In the city of Manjarūr I saw a Muslim, one of those who learn from them, for whom a platform had been raised; he stayed on top of it without eating or drinking for a period of twenty-five days, and I left him like that, so I do not know how long he stayed after me.
