Surah 56. Al-Waqia, Ayah 63

Having appealed to our own nature within us, He appeals now to the external nature around us, which should be evidence to us (1) of His loving care for us, and (2) of its being due to causes other than those which we produce and control. Three examples are given : (1) the seed which we sow in the soil; it is Allah's processes in nature, which make it grow; (2) the water which we drink; it is Allah's processes in nature, that send it down from the clouds as rain, and distribute it through springs and rivers: (3) the fire which we strike; it is again a proof of Allah's Plan and Wisdom in nature.
