[Who is] possessed of power and with the Owner of the Throne, meaning

*15) Surah An-Najm: 45, deals with the same theme, thus "It is but a Revelation which is sent down to him. One, mighty in power, has taught him. " As to what is implied by the mighty powers of the Angel Gabriel (peace be upon him) is ambiguous. In any case it at least shows that he is distinguished even among the angels because of his extraordinary powers. In Muslim (kitab- al-iman) Hadrat `A'ishah has reported the Holy Prophet's saying to the effect: "I have twice seen Gabriel in his real shape and form: his glorious being was encompassing the whole space between the earth and the heavens." According to the tradition reported from Hadrat `Abdullah bin Mas`ud in Bukhari. Muslim, Tirmidhi and Musnad Ahmad, the Holy Prophet (upon whom be peace) had seen Gabriel with his six hundred wings. From this one can have an idea of his mighty powers.
