Maryam 19:35

Ma kana lillahi anyattakhitha min waladin subhanahu itha qadaamran fa-innama yaqoolu lahu kun fayakoon

It is not [befitting] for Allāh to take a son; exalted is He! When He decrees an affair, He only says to it, "Be," and it is.

It is not for Allah to have a son. Pure is He. When He decides a thing, He simply says to it, “Be” and it comes to be.
