The questioner asks:

“Question: A man became impure after intimate relations (junub), so he performed tayyammum (ritual purification with dust when water isn’t available) and then found cold water… He is able to make Wudhu with it, but not able to perform Ghusl (Full Purification with a Bath) due to the coldness, what is the ruling on that? And, he he has no way of heating the water?
