Praying without Ghusl after having a wet dream, due to cold weather

Q 1: A young man who studies in Abha said that on Monday he slept during the afternoon and had a wet dream. He woke up and wanted to perform Janabah Ghusl (full ritual bath to cleanse of sexual discharge) but could not due to the coldness of air and water. He washed his private parts and offered Maghrib (Sunset) Prayer. Then he performed Wudu' (ablution) to offer `Isha' (Night) Prayer and offered the obligatory Prayers on Tuesday without performing Ghusl. The weather was still cold and his body could not stand the cold water. On Wednesday, he went to his family where the weather was hot, and he offered `Asr (Afternoon) Prayer there but also before he performed Ghusl. After that he performed Ghusl and offered Maghrib (Sunset) Prayer.

A: You have to repeat the Prayers you offered before having performed Ghusl and seek Allah's Forgiveness for your past negligence. (Part No. 4; Page No. 147) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
