Qur'an 3:35

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

“[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."”
