108125 we discussed bone
marrow and quoted the statement of the Islamic Fiqh Council that it is
permissible to take it from adults if that will not cause them any harm.
The Muslim will be rewarded for donating it if his intention
is sincerely for the sake of Allah and he intends to do good to the person
to whom it is donated, whether he is Muslim or non-Muslim, on condition that
he is not a harbi (a non-Muslim in a state of war against Islam), because
there is nothing wrong with showing kindness to a kaafir who is at peace
with the Muslims. Allah says (interpretation of the meaning):
“Allaah does not forbid you to deal justly and kindly with
those who fought not against you on account of religion nor drove you out of
your homes. Verily, Allaah loves those who deal with equity”
[al-Mumtahanah 60:8].
The scholars of the Standing Committee for Issuing Fatwas
were asked:
Is it permissible to transfer blood from one person to
another even if they are of different religions?
They replied: If a person is sick or is very weak and there
is no way to treat him or help him except by transferring blood to him from
someone else, and that is a way to save him, and the experts think it most
likely that it will benefit him, there is nothing wrong with treating him by
transferring blood from someone else to him, even if they are of different
religions. So blood may be transferred from a kaafir, even if he is a harbi,
to a Muslim and from a Muslim to a kaafir who is not a harbi. But in the
case of a harbi, he is not under the protection of sharee‘ah and it is not
permissible to help him. End quote.

With regard to your questions about the two methods you
described of extracting marrow and separating it, it seems that there is
nothing wrong with either of them. Determining which of them is better
should be left to specialist doctors and the method which is easiest and
least risky for the donor should be chosen.
And Allah knows best.
