A: Ruh-ul-Qudus (The Holy Spirit) is the name of Jibril (peace be upon him). `Isa (peace be upon him) is Allah's Slave, Messenger and Word, which Allah bestowed upon Maryam (Mary) and a spirit created by Allah. `Isa was called Ruh (Spirit) because Allah created him without a father. In fact Allah created him with the mere word 'Be' from the Spirit which the angel blew into Maryam (Mary) without a father.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
