From Khomeini's book, "Tahrirolvasyleh", fourth volume, Darol Elm, Gom,
1990 : A man can have sexual pleasure from a child as young as a baby.
However he should not
penetrate, sodomising the child is OK. If the man penetrates and damages the
child then he
should be responsible for her subsistence all her life. This girl, however
does not count as
one of his four permanent wives. The man will not be eligible to marry the
girls sister.
[...] It is better for a girl to marry in such a time when she would begin
menstruation at
her husband's house rather than her father's home. Any father marrying his
daughter so young
will have a permanent place in heaven. How it all began ( a long time ago in
the isolated
deserts of Arabia) : Already, when Aisha (the daughter of Abu Bakr,
Mohammad's closest friend
and unquestioning ally) was about 4-5 years old Muhammad started dreaming of
a union with her
[Ref: SAHIH BUKHARI, 5:235] and he wasted no time in realizing his dreams,
inspite of the
fact that object of his dreams was a mere child.Perhaps you want to assume
that it is
"normal" for a 50+ year old man to dream of marrying a 4-5 old child, and
then ACTUALLY ask
for her hand at 6?
