5 Preface وَالسَّماءِ وَما بَناهاYusuf AliBy the Firmament1 and its (wonderful) structure;2The next contrasted pair is the wonderful firmament on high, and the earth below our feet, stretching away to our wide horizons. The sky gives us rain, and the earth gives us food. Yet both work together: for the rain is moisture sucked up from the earth, and the food cannot grow without the heat and warmth of the sun. There are many other contrasts under this head; yet they all point to unity.The mā maṣdariya in Arabic, in this and the subsequent clauses, is best translated in English by nouns. Thus what would literally be “and the (wonderful) making or construction of it” or “the fact of its (wonderful) construction” is, idiomatically, “its (wonderful) structure.” “The (wide) spreading out” of the earth is rendered “its (wide) expanse,” and so on.
