about how so many antibodies can be produced by a
limited number of genes.
As outlined in detail in the section on "Antibodies",
the B cells use the genes in the human body to manufac-
ture antibodies. However, the number of genes in the
human body is less than the number of antibodies pro-
duced. This situation causes no problem for the cells.
Despite all these limitations, they succeed in producing
9
nearly 2 million antibody types an hour. B cells interact in
various combinations with available genes to make the
above-mentioned production. It is literally impossible for
a cell to think up these combinations. These unconscious
cells are given the ability to involve themselves in these
combinations by the will of Allah. This is because "...
When He decides on something, He just says to it,
‘Be!' and it is." (Surat al-Baqara:117)
No other force in the heavens and on the earth save
Allah is capable of ordering even a single feature of the
trillions of cells. It becomes possible only by the will of Al-
lah that a cell performs such mathematical operations as
producing the most appropriate weapon to inactivate
every enemy that has invaded the cell.

Brave Warriors: T Cells
Some lymphocytes migrate to the thymus after they
are manufactured in the bone marrow. The lymphocytes,
which multiply and mature here, are called T cells. These
cells mature to form two different types: killer and helper
T cells. After a three-week education, T cells migrate to
the spleen, lymph nodes, and intestinal tissues to wait for
the time of their mission.
