The more we ponder over the above verse, we may extract more versions of meanings. As a matter of fact, many of the Quränic verses include several meanings. Some of them are simple for common people's understanding, for all ages, and places; and some are very deep, and the learned and scholars understand them. Meanwhile, the various meanings are not contrary to one another! The above verse is among the complex ones with manifold of meanings.
The first meaning that we may point to is the method by which the primitive Arabs were kindling their fires. They use two pieces of wood from two kinds of tree that they called, ``MARKH'' and ``AFÄR''.
They moved and rubbed one over the ther, and a spark was produced, by which they lit their fire. This was just like a flint or a piece of quartz which strikes fire with steel. This means, was used instead of our present day's matches, among Arabs in the Pagan Era, and hence:-
``He Who made for you fire out of a green tree, and from it you kindle your fire.''
The second meaning that we may apprehend from the verse is that, Allah Who produces fire from water is He Who produces life out of death!
