“[He is] the One Who knows the unseen and the seen, the Great, the Most High”
(13:9) The Holy Quran
“Allah doth know what every female (womb) doth bear, by how much the wombs fall short (of their time or number) or do exceed. Every single thing is before His sight, in (due) proportion. He knoweth the Unseen and that which is open: He is the Great, THE MOST HIGH. It is the same (to Him) whether any of you conceal his speech or declare it openly; whether he lie hid by night or walk forth freely by day.”
(13:8…10) The Holy Quran
From the root 'a-l-w with the classical Arabic connotations: to be high, elevated, lofty to be exalted, to rise up, to ascend to be higher to exceed, surpass to overcome, overwhelm to advance, promote, rise above to mount, be overtop, eminent.
