One of the ways one can appreciate what it means to be omniscient is to consider that Allah knows things that are unimportant to us in any conceivable way. Of course, what makes these things seem unimportant is our ignorance of the whole.
Surat Al-An’am 6:59
۞ وَعِندَهُ مَفَاتِحُ الْغَيْبِ لَا يَعْلَمُهَا إِلَّا هُوَ ۚ وَيَعْلَمُ مَا فِي الْبَرِّ وَالْبَحْرِ ۚ وَمَا تَسْقُطُ مِن وَرَقَةٍ إِلَّا يَعْلَمُهَا وَلَا حَبَّةٍ فِي ظُلُمَاتِ الْأَرْضِ وَلَا رَطْبٍ وَلَا يَابِسٍ إِلَّا فِي كِتَابٍ مُّبِينٍ
And with Him are the keys of the unseen; none knows them except Him. And He knows what is on the land and in the sea. Not a leaf falls but that He knows it. And no grain is there within the darknesses of the earth and no moist or dry [thing] but that it is [written] in a clear record.
Consider what it means to know whenever a leaf falls anywhere—on planet earth or any other place in the universe. When we think about knowing everything, we think more about, say, the “theory of everything.” And of course, only Allah keeps the “clear record.” We might think it superfluous to record every moist and dry thing in existence, but when examining the genetic code (for this discussion of Surah 112), I found that the hydrophobicity (water-repelling) or hydrophilicity (water-accepting) of “codons” (the building blocks of DNA) directly relates to their functionality, and how all life is created and differentiated. So this rather unheralded statement of seemingly unnecessary knowledge is “key” to the genetic code!
And there is so much in the Quran hinting at knowledge we’ve only begun to know even exists. Then one thinks about mathematical ideas and such unimaginably complex geometrical forms as E8, described here, where it is summed up as being “an abstract concept of symmetry, that is found in a ‘ball’ of 240 points in 8 dimensional space.” The picture at the top is a 2-dimensional projection of E8, considered beyond the capacity of the human mind to comprehend in 8 dimensions. Physicists interested in string theory hope it may unlock the longed-for “theory of everything,” but one wonders how something incomprehensible to us could itself “explain” everything to us.
But in any case, Allah alone has the true and detailed knowledge of all things. Then to imagine that this same Allah the Exalted Omniscient sent the Quran to us as a guide — one wonders why people of understanding are not even curious to examine it in more details! Perhaps containing a theory of everything that is not limited to physics or mathematics or empirical data. But rather, encompassing them, including helping us with that ignored and forgotten conundrum, how to tell right from wrong. Now there’s a problem even E8 can’t answer for us. It’s rather astounding that people of intelligence have to even bothered to consider what a powerful book this is.
