"Scientists call this a biological clock," his grandfather ex-
plained. "The clocks that make time adjustments for plants calcu-
late how long sunlight falls on the leaves for. These biological
clocks calculate this length of time differently for every plant. For
example, as a result of experiments done on soy beans, we know
that these plants bloom every year at the same time, no matter
when they are planted. It is certainly Almighty Allah Who makes
these time adjustments in plants."
Grandpa Hassan and his grandson stopped by an orchard next
to the road. After receiving permission from the owner, they picked
some plums, washed them carefully and began to eat them. They
were really delicious. Grandpa Hassan said, "Did you know,
Kareem, that the energy plants give us actually comes from the
Sun?"
