What was narrated by Muhammad ibn Ya‘qub, from a group (of our companions), from Ahmad ibn Muhammad, from al-Husayn ibn Sa‘id, from his brother al-Hasan, from Zur‘ah, from Sama‘ah, who said: I asked Him عليه السلام about a man who is in a deserted land and has only one garment, and he becomes in a state of major ritual impurity (junub) in it, and he does not have water, what should he do? Imam عليه السلام said: "He performs tayammum and prays naked, seated, and gestures (for bowing and prostration)."
