Surah Maryam (Mary), Verse 35

مَا كَانَ لِلّٰهِ اَنْ یَّتَّخِذَ مِنْ وَّلَدٍ سُبْحٰنَهٗ اِذَا قَضٰۤی اَمْرًا فَاِنَّمَا یَقُوْلُ لَهٗ كُنْ فَیَكُوْنُ ۟

Maa kaana lillaahi ai yattakhiza minw waladin Subhaanah; izaa qadaaa amran fa innamaa yaqoolu lahoo kun fa yakoon

“It is not befitting to (the majesty of) Allah that He should beget a son. Glory be to Him! when He determines a matter, He only says to it, "Be", and it is.”

Quran 19:35 (Yusuf Ali Translation)
