What is the ruling on removing major ritual impurity by washing only the private parts and performing ablution if the water is extremely cold?

Question:
A questioner says: I woke up from sleep in a state of major ritual impurity, and I wanted to take a full ritual bath, but I found the water cold, so I was unable to take a full ritual bath with it. So I got up, performed ablution, and washed my private parts. Is my action correct?

Answer:
It is not correct. If the water is extremely cold and you cannot bear to use it, and you have nothing to heat it with—no fire, no gas, nothing, no electricity—and it is extremely cold and there is danger to you in using it, then it is permissible for you to perform dry ablution with clean earth and pray.
Just as 'Amr ibn al-'As (may Allah be pleased with him) did on one of his journeys when he had a wet dream and the water was extremely cold. He performed dry ablution with clean earth (may Allah be pleased with him) and prayed, and he mentioned this to the Prophet (peace and blessings be upon him), so he approved it for him. But if you have something with which you can heat the water, it is not permissible for you except to take a full ritual bath. Heat the water, take a full ritual bath, and pray. Yes.
