Surah Aali Imran (The Family of Imran), Verse 47

قَالَتْ رَبِّ اَنّٰی یَكُوْنُ لِیْ وَلَدٌ وَّلَمْ یَمْسَسْنِیْ بَشَرٌ قَالَ كَذٰلِكِ اللّٰهُ یَخْلُقُ مَا یَشَآءُ اِذَا قَضٰۤی اَمْرًا فَاِنَّمَا یَقُوْلُ لَهٗ كُنْ فَیَكُوْنُ ۟

Qaalat Rabbi annaa yakoonu lee waladunw wa lam yamsasnee basharun qaala kazaalikil laahu yakhluqu maa yashaaa'; izaa qadaaa amran fa innamaa yaqoolu lahoo kun fayakoon

“She said: "O my Lord! How shall I have a son when no man hath touched me?" He said: "Even so: Allah createth what He willeth: When He hath decreed a plan, He but saith to it, 'Be,' and it is!”
