It is not [befitting] for Allah to take a son; exalted is He! When He decrees an affair, He only says to it, "Be," and it is.
The Saheeh International Quran Translation
مَا كَانَ لِلَّهِ أَن يَتَّخِذَ مِن وَلَدٍ سُبْحَٰنَهُۥٓ إِذَا قَضَىٰٓ أَمْرًا فَإِنَّمَا يَقُولُ لَهُۥ كُن فَيَكُونُIt is not [befitting] for Allah to take a son; exalted is He! When He decrees an affair, He only says to it, "Be," and it is.
