The semen from which man is developed is pure

Q: Is the semen from which man is created pure or not? If it is not impure what is the wisdom behind Ghusl (ritual bath following major ritual impurity)? Is it prohibited to delay Ghusl until the morning in winter for fear of the cold weather?

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. The sound opinion is that semen is pure. When it is ejaculated in spurts from a person lustfully through sexual intercourse or a wet dream, Ghusl is compulsory. It is permissible to delay it until morning. A person should take Ghusl to offer Fajr (Dawn) Prayer in its due time. It is not permissible to delay it until the prayer due time is over. (Part No. 5; Page No. 320) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
