According to Islamic scriptures, Jibreel (جبريل Gabriel) is the angel who first appeared to Muhammad in the cave of Hijra and taught Muhammad the Qur’an
The Qur’anic verses 21:91 and 66:12 in conjunction with the tafsir’s, tell us he was sent to breathe Allah’s spirit into Maryam’s (Mary’s) vagina.
(And We breathed into it (private part) through Our Ruh,) meaning, through the angel Jibril. Allah sent the angel Jibril to Maryam, and he came to her in the shape of a man in every respect. Allah commanded him to blow into a gap of her garment and that breath went into her womb through her private part; this is how `Isa was conceived.
