Why is it that a garden is sometimes green and sometimes yellow?

Why is it that the deserts are dry and the mountaintops are covered with snow?

Why is it that the color of the sun is like fire when rising and like blood when setting?

Why is it that the moon turns from a beautiful full moon to a slim crescent?

There are so many 'whys' which I cannot find the answer for. All I know is that I was a plant, then I became an inanimate object and then I turned into an animal. I know that my last transformation, from an object to an animal, was one of Allah's great Miracles. To Musa I was only a staff but to Almighty Allah I was something totally different.

The staff of Prophet Musa (Moses), that is me.
