47. "she said: 'my lord! how can l have a child when no man has
touched me?'
he said: 'even so allah creates what he pleases.
when he decrees a matter (to be), he only says to it 'be!' and it is'."

commentary:
the will of allah is the cause of creation and he can create
without any material means or material cause. allah is the cause of all
causes sometimes he takes the effect of a thing from it and sometimes
gives a particular effect to a thing the appearance of existence, the
maintenance of existence, the effects of existence, and the quantity, the
quality and the duration of the effects of all things depend on the will
and pleasure of allah the qur'an, in answer to the request of
zachariah, says:
"even so does allah whatsoever he pleases."1 while in
answer to mary it says:
"even so allah creates what he pleases" the
secret of this difference - does & creates - in the statement may lie in
this that a child coming forth from a lady without being touched with a
spouse is more surprising than that an old man brings an offspring from
his old wife

then, to complete this meaning, the qur'an says:

" ... when he decrees a matter (to be), he only says to it 'be!' and it is'."

explanations:
1. allah is powerful in creation he can create creatures both
through the natural means and without natural means. both of them
are the same for him,

"... he said: `even so allah creates what he pleases
when he decrees a matter (to he), he only says to it `be!' and it is '."

2. allah's creation through an unusual way is not a new thing
this manner has had some former samples, too.

3. it does not matter for a person to wonder and ask question
when its origin is not denial and obtimacy.

"she said: `my lord! how can i have a child when no man has
touched me ? '..."
