Hearing this, Maryem said, “O my Lord! How can I have a son when no man has ever touched me?” He replied, “Even so, Allah creates however He wants; whenever He decides to do anything, He only says it to ‘Be’ and it is!.
Meaning:
“Be, and it is“: whenever God intends for something to exist, He simply commands it to “Be,” and it instantly comes into existence.
