One who performed wudu and prayed Fajr due to the severe cold, then took a ghusl after the weather warmed up

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: I was in the desert and the cold was severe. He says: I was in the desert and the cold was severe, so I had a wet dream that night and I was unable to take a ghusl because of the severity of the cold. So I performed wudu and prayed Fajr. Then when the sun rose and the weather became warm, I took a ghusl.

Answer:
This is a mistake. You should have performed tayammum and prayed. You should have performed tayammum and prayed Fajr. As long as you do not have water that is severely cold and there is danger to you, or nothing with which to warm the water, perform tayammum, my brother, and pray. Pray at its time. So when it becomes, meaning, during the day and the water warms up, you take a ghusl for the future, not for the one that has passed. You will take a ghusl for the future. Yes.
