Assalaam Alaikum Wa Rahmatullahi Wa Barakatuh,
We can know and feel the greatness of Allah SWT by His acts in universe.The Being that creates and then administers at a single time and in a single fashion the stars that are thousands of years distant from each other; that creates at a single time and in a single form the countless members of the same species of flower, distributed over the east and the west, the north and south of the globe; that administers, nurtures, quickens, distinguishes and adorns more than two hundred thousand different types of plant and species of animal in five or six weeks, with the utmost regularity and equilibrium, without any confusion, defect or error, in order to provide every spring on the face of the earth more than a hundred thousand specimens of the supreme resurrection, and thus prove before man’s eyes a remarkable event, now belonging to the past and the realm of the Unseen, namely the creation of the heavens and the earth in six days, as indicated in the verse,
"He it is Who created the heavens and the earth in six days;" Qur’an, 57:4.
the Being that causes the earth to revolve, as evidenced in the verse,
"He merges night with day, and day with night," Qur’an, 3:27.
and turns the night into the page on which the events of the day are written - this same Being knows and administers according to His own will, all at the same time, the most secret and obscure thoughts that occur to men’s hearts. Since each of the aforementioned acts is in reality one act, it follows that their Glorious Doer is a Unique and Powerful Being, enjoying such grandeur and sublimity that nowhere, in nothing, in no way, does it leave the slightest possibility for the acceptance of partnership; on the contrary, it uproots all such possibility.
Since such sublime power and grandeur exist and since that grandeur is at the very apex of perfection and comprehends everything, it is certainly in no way possible to permit or allow any attribution of partners to that Unique and Powerful Being, for so doing would ascribe impotence or need to that power, fault to that grandeur, defect to that perfection, and impose restriction on that comprehensiveness. No sound intellect could deem this possible.
