Kaana
?? when used for Allah Almighty it means what I described in the previous post, because it indeed is the closest word that can give us a simple picture of His Infinity. Allah Almighty did use YAKOON (2:117), which is present of Kaana, when the Almighty Said when He wants to create something He commands it "be and
it becomes" (2:117). Here YAKOON was used, because it has beginning and end
(all shall taste death) 3:185 ??

?? . But with Allah Almighty past tense encompasses all past and present and future. There is nothing comparable to Allah Almighty
(112:004). Our earthly grammar does not encompass Allah Almighty. But the use of past tense is the most appropriate.
In a nutshell, before anything and everything was Allah Almighty. Hence the use of past tense for Allah Almighty.
