                     A Manifestation of God’s Attributes of

              The Most Compassionate and The Most Merciful


                Feeling pain or discomfort plays a very important role in our lives, because
             these sensations notify us that there is a problem in our bodies. When the re-
             ceptors in our skin react to things that are harming us and send urgent mes-
             sages to the brain, we can then take measures to allay that discomfort.
