While we are still a single cell, as yet unformed, in our mother’s wombs, some of the cells that make up our bodies decide to become the heart, and others to form the eye. Unconscious cells turn into exceedingly complex organs through the will of Allah (God). From that moment, the cells that Allah commands to turn into the heart commence beating, and continue doing so until we draw our last breaths. The heart continues beating uninterrupted as we run, walk, work and even sleep. Although people are unconscious when they are asleep, the way the heart still keeps beating is a miracle that takes place by Allah’s choosing. The way that Allah keeps our hearts beating is a great blessing, because we have no power to keep the heart beating regularly, or to speed it up or slow it down as necessary. Allah has mercy on human beings by maintaining that blessing. Allah’s creation is described as follows in one verse:
Glorify the Name of your Lord, the Most High: He Who created and molded; He Who determined and guided. (Surat al-A‘la, 1-3)
