Dought & clear, - Some of the signs of puberty appeared in her daughters at the age of six; what should she do?

I have been blessed with 2 healthy daughters. When my older daughter
was 5 she started getting hair under her arm by the age she was 6 they
were full pubic hair and by the age she was 7 she began getting breast
buds, she is now 8. My younger daughter had vaginal hair from age 3
now she is 6 also has hair under arms. My question is does this mean
that my children have reached puberty and now will be judged for their
actions. They are still very small and dont understand understand
anything. this has me very upset.
Praise be to Allah.
Puberty is recognised by signs that have been defined by the scholars,
one of which is the growth of hair in certain places on the body.
The hair which signals puberty is the pubic hair that grows around the
penis in males and the vulva in females. With regard to armpit hair,
the beard and moustache, the growth of any of these does not signal
puberty. Moreover, it is not just any hair growing in the pubic region
that signals puberty; rather what counts in this case is that the hair
should be coarse and need to be shaved with a razor and the like. In
the case of fine hair that does not need to be shaved, this does not
signal puberty.
Please see the answers to questions no. 138738, 192334and 175405for
more details on this matter.
If any of the signs of puberty have appeared in your daughters, as
mentioned above, then this means that whoever has these signs appear
in her body has reached the age of accountability and responsibility.
There is no negative impact for you or your daughters, in sha Allah;
rather this is something that Allah has decreed for them, and we have
to cope with it by adhering to the limits set by Allah, not
transgressing them, and by respecting them. What you have to do is
raise your daughters in that manner, and pay attention to them, advise
them, teach them and ask Allah to protect them from error and not to
burden them with more than they can bear. You will be rewarded for all
of that, in sha Allah.
However it is very possible that there is some kind of imbalance in
their hormones or glands that has led to this, because the appearance
of these signs at an early age gives rise to concern. Hence we advise
you to take your daughters to a specialist doctor, because perhaps
they need medical attention.
May Allah help you and protect your daughters, and cause them to grow
up well and strong, and may He help you to give them a good Islamic
upbringing.
And Allah knows best.
