The Staff of Prophet Moses (Musa)

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. I am the staff of Musa. I preceded the Prophet while walking ...I would raise high then fall down onto earth all the way along. I have no mind and I know nothing about "why" or "how". At first the sun used to provide me with greenness and elasticity, but when I died it gave me strength and solidity, how amazing! Death is supposed to be the end of power and strength for all beings, but for me it was the opposite. I was only a branch of a tree and when I died I became stronger. So, you see that death means the ultimate end of power for some beings and a newborn power for others.
