If you say: How can we know all the meanings in the examples you have given, which the Qur'an intends and points to?
We would reply: Since the Qur'an is a pre-eternal address, and sitting above and beyond the centuries, which, layer upon layer, are all different, addresses and instructs all of mankind lined up within them, certainly it will include and intend numerous meanings according to those varying understandings, and will make allusions to what it intends. The numerous meanings contained in the Qur'an's words similar to those mentioned here have been proved in Isharat al-I'jaz (Signs of Miraculousness) according to the rules of Arabic grammar, and the sciences of rhetoric, semantics, and eloquence and their rules. According to the consensus of those qualified to interpret the Shari'a and the Qur'anic commentators and scholars of theology and jurisprudence, and according to the testimony of their differences, on condition they are considered correct by the sciences of Arabic and the principles of religion, all the aspects and meanings which are found acceptable by the science of semantics, and appropriate by the science of rhetoric, and desirable by the science of eloquence, may be considered among the meanings of the Qur'an. The Qur'an has placed allusions to each of those meanings according to its degree. They are either literal or significative. If significative, there are allusions to them in either the preceding context or the after context or in other verses. Some of them have been expounded in Qur'anic commentaries of twenty, thirty, forty, sixty, and even eighty volumes, written by exacting scholars, which are clear and decisive proofs of the extraordinary comprehensiveness of the Qur'an's words. However, if in this Word we were to point out the allusions indicating all the meanings together with their rules, the discussion would become extremely prolonged. So we cut it short here, and for part of it, refer you to Isharat al-I'jaz-
Second Flash: This is the extraordinary comprehensiveness in its meaning. Yes, together with bestowing from the treasuries of its meaning the sources for all the interpreters of the Shari'a, the illuminations of all those seeking knowledge of God, the ways of all those seeking union with God, the paths of all the perfected from among mankind, and the schools of all the scholars, the Qur'an has at all times been the guide of all of them and directed them in their progress, and it is verified unanimously by all of them that it has illuminated their ways from its treasuries.
Third Flash: This is the extraordinary comprehensiveness in its knowledge. The Qur'an has caused to flow forth from the oceans of its own knowledge, the numerous and various sciences of the Shari'a, the multifarious sciences of reality (haqiqat), and the innumerable different sciences of sufism (tariqat). Similarly, it has caused to flow forth in abundance and good order the true wisdom of the sphere of contingency, the true sciences of the sphere of necessity, and the enigmatic knowledge of the sphere of the hereafter. One would have to write a whole volume to provide examples of this Flash, and so as mere samples, we point to the twenty-five Words so far written. Yes, the veracious truths of all twenty-five Words are only twenty-five droplets from the ocean of the Qur'an's knowledge. If there are errors in those Words, they spring from my defective understanding.
