            vader, they rapidly divide and start to produce antibodies. These antibod-
            ies bind to microbes like B cell receptors. The enemy cells that are marked
            by the antibodies as foreigners are driven out of the body at the end of the
            relentless struggle of phagocytes and T cells. By the time the B cells inac-
            tivate the enemy with the millions of antibodies they have produced, they
            have also marked it for killer cells. Here, there is another important point,
            which is as important as destroying and marking foreign cells. It is 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 manufacture antibodies. However, the num-
            ber 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 nearly 2 million antibody types an
                 9
            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 possi-
            ble only by the will of Allah that a cell performs such mathematical oper-
            ations as producing the most appropriate weapon to inactivate every en-
            emy that has invaded the cell.



                 Brave Warriors: T cells
                 Some lymphocytes migrate to the thymus after they are manufac-
            tured in the bone marrow. The lymphocytes, which multiply and mature
            here, are called T cells. These cells mature to form two different types: kill-
            er 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.
