The document discusses the biological formation of milk according to modern science and how it aligns with verses from the Quran. The basic materials from digested food pass through the intestine wall into blood and reach organs, including milk glands. Milk is then secreted with high nutritional values after this process. The Quran describes milk as being formed from the contents of cattle bellies and blood, which aligns with scientific understanding that milk is produced from digested food carried by the blood.

6. THE FORMATION OF MILK
There is instruction for you in
cattle. From the contents of their
bellies, from between the dung
and blood, We give you pure milk
to drink, easy for drinkers to
swallow. (Qur'an, 16:66)

7. THE FORMATION OF MILK
The basic materials which allow the
nourishment of the body come about
as a result of chemical changes in the
digestive system. These digested
substances then pass through the wall
of the intestine into the blood stream.
Due to the circulation of the blood, the
nutriments reach the relevant organs.

8. THE FORMATION OF MILK
Like the other bodily tissues, the milk glands are
nourished by nutriments brought to them by the
blood. The blood therefore plays a most
important role in the collection of nutriments
from foodstuffs. Milk is secreted by the milk
glands after all these stages and its nutritional
values are particularly high.

9. THE FORMATION OF MILK
Human beings are unable to directly
consume either the half-digested food in
an animal’s stomach or an animal’s
blood. Furthermore, the direct
consumption of these or any of their
compounds can lead to severe illness,
and even death. Thanks to the
exceedingly complex biological systems
He has created, Allah provides clean and
healthy food for human beings from
these fluids.

10. THE FORMATION OF MILK
This is because it forms as a result of
digested food being carried by the
blood. High-nutrition milk is thus
produced from blood, which cannot be
consumed directly, and semi-digested
food.

11. THE FORMATION OF MILK
The formation of milk is by itself an
enormous creation miracle. And it is
another miracle altogether that such
detailed information about that
formation should be contained in the
Qur’an.

12. THE FORMATION OF MILK
As we have seen, the information
about the biological formation of milk
in Surat an-Nahl 66, is in great
accordance with the facts established
by modern science. It is quite clear
that such information, requiring
detailed knowledge of mammals'
digestive systems, could not have
been known at the time when the
Qur'an was revealed.
