16. And mention in the Scripture Mary, when she withdrew from her people to an eastern location.
17. She screened herself away from them, and We sent to her Our spirit, and He appeared to her as an immaculate human.
18. She said, “I take refuge from you in the Most Merciful, should you be righteous.”
19. He said, “I am only the messenger of your Lord, to give you the gift of a pure son.”
20. She said, “How can I have a son, when no man has touched me, and I was never unchaste?”
