Aal-'Imran - 3:35

إِذْ قَالَتِ امْرَأَةُ عِمْرَانَ رَبِّ إِنِّي نَذَرْتُ لَكَ مَا فِي بَطْنِي مُحَرَّرًا فَتَقَبَّلْ مِنِّي إِنَّكَ أَنتَ السَّمِيعُ الْعَلِيمُ
[3:35]
When a woman of Imran said: My Lord! surely I vow to Thee what is in my womb, to be devoted (to Thy service); accept therefore from me, surely Thou art the Hearing, the Knowing.
Behold! a woman of 'Imran said: "O my Lord! I do dedicate unto Thee what is in my womb for Thy special service: So accept this of me: For Thou hearest and knowest all things."
(Remember) when the wife of 'Imran said: My Lord! I have vowed unto Thee that which is in my belly as a consecrated (offering). Accept it from me. Lo! Thou, only Thou, art the Hearer, the Knower!
