Dead leaves falling onto the soil are a valuable source of food for many living things.
Fallen leaves contain nutrients that can be used by insects, fungi and bacteria. These nutrients are altered by micro-organisms and enter the soil. Trees are also able to use their roots to take these nutrients back from the soil.
In addition, fallen leaves set up a layer of mulch on the forest floor, thereby helping to retain and absorb rainfall.
As well as all this, many living things hide under leaves for protection against external agents.
Allah has made the autumn as an immaculate visual display for us as the leaves turn from green to red or orange, an instrument of great wisdom for all living things.
With the coming of spring, Allah restores to life the trees whose leaves have fallen in the autumn and stand through the winter months with bare branches. And with the brightly colored blossoms and green leaves that sprout from those dry branches, we witness an immaculate artistry.
This is without doubt one of the matchless works Allah’s artistry, He, Who creates flawlessly and with sublime knowledge.
I seek refuge with Allah from the accursed satan
... Allah did not create the heavens and the earth and everything between them except with truth and for a fixed term. (Surat ar-Rum, 8)
