Is the Sawm of a Junub who delays taking Ghusl valid?

Q 1: A person intended to observe voluntary Sawm (Fasting) on Thursday, for example. He slept after having Suhur (pre-dawn meal before the Fast), but on the next day he found himself Junub (in a state of post-sexual ritual impurity) and did not find water at home. There was water in the Masjid (mosque) which was nine kilometers away. This long distance presented no problem; the problem was his fear that his father might need him during the time he would take to go to the Masjid and ask him where he was, why he went there, and might even prevent him from going. He, thus, did not perform Janabah Ghusl (full ritual bath to cleanse of sexual discharge) that night and did not observe Salah (Prayer) for a whole day. On the next day, he performed Janabah Ghusl without his father's knowledge and made up for the Salah he missed the day before. Is his Sawm valid or not?

A: Anyone person who becomes Junub must perform Ghusl. It is not lawful to delay Ghusl until after the prescribed time of Salah elapses. The possibility that his father might scold him was not an excuse (Part No. 4; Page No. 156) for delaying Ghusl as long as he was able to use water. His Sawm, on the other hand, is valid, but he is a sinner for delaying Salah beyond its prescribed time. He should make Tawbah (repentance to Allah) and ask Allah's Forgiveness for what he did.
