              increases its tempo to pump around 2,270 liters (560 gallons) of blood an
                   48
              hour. That is because our muscles need more oxygen when performing
              tiring activities. Under such circumstances, the heart increases its work-
              ing tempo from 70 to 180 times a minute, and the level of blood reaching
              the tissues can increase five-fold.
                   No man-made pump can match the heart’s ability to work tirelessly
              for an entire lifetime and to regulate the quantity pumped according to
              prevailing circumstances. The extraordinary nature of the heart reveals
              an important fact. God created many matchless structures, such as the
              heart, in the billions of human beings. And as revealed in the Qur’an,
              this is an easy matter for Him:
                   Your creation and rising is only like that of a single self. God is All-
                   Hearing, All-Seeing. (Surah Luqman, 28)



                                                           The heart carries blood and all
                                                           essential substances to the
                                                           cells throughout the body, and
                                                           when it can no longer function,
                                                           death ensues. Like all other or-
                                                           gans in the body, it runs on
                                                           electricity; but this energy that
                                                           allows the heart to beat does

                                                           produced with the contraction
                                                           of the heart muscles. Since the
                                                           heart consists almost entirely of

                                                           times a minute, then an electri-

                                                           current reaches them. The
