*4) That is, He alone is the Creator of the universe as well as Its Ruler. (For further explanation, see E.N.'s 41, 42 of AI-A'raf, E.N.4 of Yunus, E.N.'s 2 to 5 of Ar-Ra'd, E.N,'s 11 to 15 of Ha Mim As-Sajdah).
*5) In other words, He is not only the Knower of the wholes but also of the parts. He knows each seed that goes under the layers of the soil, each leaf and bud that comes out of the soil, each rain-drop that falls from the sky, and each molecule of the vapour that ascends from the seas and lakes to the sky. He is aware of every seed Iying anywhere under the soil. That is how He causes it to split and sprout up and develop. He Is aware of how much vapour has risen from each different place and where it has reached. That is how he collects it into cloud and distributes it and causes it to fall as rain in due measure on different place of the earth. The same is true of the details of everything that goes into the earth and comes out of it, and of everything that ascends to the sky and descends from it. If aII this were not comprehended by Allah in His knowledge, it would not be possible for Him to plan and order each thing separately and to regulate and control it in a wise manner.
*6) That is, "Nowhere are you outside Allah's knowledge, His power, His rule, His management and administration. Allah knows wherever you are, whether in the earth, or the air, or the water, or in a secret place. Your being alive there is by itself a proof that Allah is providing for you in that very place. If yow heart is beating, if your lungs are breathing, if yow hearing and yow sight arc functioning, it is only because all parts of yow body are working under Allah's rule. And if death comes to you at any place; it comes because Allah takes a decision to stop providing for you and to recall you from the world."
