Wet dreams in the desert with severe cold and inability to perform ghusl

The questioner:
He says: May Allah reward you. A man had a wet dream while he was in the desert, the weather was cold, and he could not perform ghusl for fear of falling ill,

The Shaykh:
Hmm.

The questioner:
and he was in the desert, the weather was cold, and he could not perform ghusl for fear of falling ill, so what should he do?

The Shaykh:
If he has nothing to heat the water with, no light, no gas, or anything else, and he fears for his life from the cold, he performs tayammum. 'Amr ibn al-'As (may Allah be pleased with him) was leading a detachment when he became in a state of major ritual impurity and feared for his life from the cold, so he performed tayammum and led his companions in prayer. He had a wet dream during the night, so he performed tayammum and led his companions in prayer. When he came to the Messenger (peace and blessings be upon him), he informed him, and the Messenger approved of that. Yes.
