Quran 39:4 Az-Zumar, ayah 4 of 75

لَّوْ أَرَادَ ٱللَّهُ أَن يَتَّخِذَ وَلَدًا لَّٱصْطَفَىٰ مِمَّا يَخْلُقُ مَا يَشَآءُ ۚ سُبْحَـٰنَهُۥ ۖ هُوَ ٱللَّهُ ٱلْوَٰحِدُ ٱلْقَهَّارُ ۝٤

39:4 If Allah had willed to choose a son, He could have chosen what He would of that which He hath created. Be He Glorified! He is Allah, the One, the Absolute.
