plained. "The clocks that make time adjustments for plants calcu-

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."

Kareem, that the energy plants give us actually comes from the

Sun?"
