Quran 3:42 — The Amramites (Ali-'Imran)

The angels said, "O Mary, GOD has chosen you and purified you. He has chosen you from all the women.

[3:41] He said, "My Lord, give me a sign." He said, "Your sign is that you will not speak to the people for three days, except through signals. Commemorate your Lord frequently; and meditate night and day."

[3:43] "O Mary, you shall submit to your Lord, and prostrate and bow down with those who bow down."
