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

وَإِذ قالَتِ المَلٰئِكَةُ يٰمَريَمُ إِنَّ اللَّهَ اصطَفىٰكِ وَطَهَّرَكِ وَاصطَفىٰكِ عَلىٰ نِساءِ العٰلَمينَ

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."
