Ali 'Imran 3:35

إِذْ قَالَتِ ٱمْرَأَتُ عِمْرَٰنَ رَبِّ إِنِّى نَذَرْتُ لَكَ مَا فِى بَطْنِى مُحَرَّرًا فَتَقَبَّلْ مِنِّىٓ ۖ إِنَّكَ أَنتَ ٱلسَّمِيعُ ٱلْعَلِيمُ

Idh qālati im'ra-atu ʿim'rāna rabbi innī nadhartu laka mā fī baṭnī muḥarraran fataqabbal minnī innaka anta l-samīʿu l-ʿalīmu

[Mention, O Muḥammad], when the wife of ʿImrān said, "My Lord, indeed I have pledged to You what is in my womb, consecrated [for Your service], so accept this from me. Indeed, You are the Hearing, the Knowing."
