He Who has made for you and for all human beings fire from the green tree namely from the markh and ‘afār variety or from all trees except for the jujube ‘unnāb and behold from it you kindle’ from it you strike fire this is proof of the power of God to resurrect for in this example of the green tree He has combined the elements of water fire and wood; but neither the water extinguishes the fire nor does the fire ignite the wood.
