Meaning of the aayah “His is the highest description”
Question

Allaah says (interpretation of the meaning): “His is the highest description (i.e. none has the right to be worshipped but He, and there is nothing comparable unto Him) in the heavens and in the earth” [al-Room 30:27] Does mathal [translated here as “description”] mean likeness?
Praise be to Allah.and blessings and peace be upon the Messenger of Allaah.
The phrase “al-mathal al-‘alaa (translated here as ‘the highest description’)” means the highest description in all aspects. For Allaah has the attribute of absolute perfection in all senses, as He says (interpretation of the meaning):
“There is nothing like Him, and He is the All-Hearer, the All-Seer”
[al-Shoora 42:11] 
“Say (O Muhammad): He is Allaah, (the) One.
Allaah-us-Samad [Allaah — the Self-Sufficient Master, Whom all creatures need, (He neither eats nor drinks)].
He begets not, nor was He begotten.
And there is none co-equal or comparable unto Him.”
[al-Ikhlaas 112:1-4]
And Allaah is the Source of strength.
