Zümer 21:

• Görmüyormusunuz ki, Allah(cc) gökten yağmuru indiriyor, onu su kaynakları olarak yeryüzünde akıtıyor, ve onunla rengarenk ekinler çıkartıyor. Daha sonra onlar kuruyor ve siz onları sararmış görürsünüz, sonra da çer-çöp haline dönüşürler. Elbette bunlarda, akıl-iz'an sahipleri için çıkartılacak çok ders vardır.

  That is, "A man of understanding learns this lesson from it that the life of this world and its adornments are all transitory: the end of every spring is autumn; the fate of every youth is weakness and death; and every rise has a fall. Therefore, this world is not something of which one should be charmed and enamored so as to forget God and the Hereafter and should conduct himself here in a manner as to nun his Hereafter, only for the sake of enjoying the short lived pleasures of this world. Then a man of understanding also learns this lesson from these phenomena that the spring and autumn of this world are only under Allah's control: Allah allows to grow and prosper whomever He wills and ruins and lays waste whomever He wills. Neither it is in anybody's power to stop the growth of someone whom Allah wills to grow, nor has anyone the power to save him from destruction whom Allah wills to destroy.ET
