verse (شيء) is considered as most significant Quranic verse which is considered as the root of monotheism.
Misliyat in Arabic means example
There is nothing example compare to ALLAAH
three levels. I.e (صفت اسماء)
"Dhaat" "Sifath" "Asma*
Level 1 : Divinity
Level 2: Divine Attributes
Level 3: Beautiful Names
ALLAAH is unparalleled in divinity or in His attributes or in His beautiful names. That is what this beautiful sentence says he is Inimitable. We cannot compare him to any character in terms of his divinity & Glory . Nor can we compare his qualities with anyone else.
Human's character keeps on changing constantly. For example, one who is ready to donate / grant to give today might become stingy tomorrow. Likewise one can be empathetic today might tend become very angry tomorrow but the attributes of Allah will remain unchanged.

And even in name he cannot be compared to anything. He is the owner of all the beautiful names. In Holy Quran Allah extolls in many verses which says that He is the One Supreme , Most Unique , He is the One who is made of light, He does not receive anyone, He is not received by anyone. In this verse the Lord has many signs for the atheists i.e. there is no doubt that even if the atheists examine this verse they will all accept Islam as their way of life. ALHAMDU LILLAH.
