What is the ruling on saying "And to Allah belongs the highest example" before or after mentioning examples, and what is its meaning? Is the lam in "lillah" for possession? What is the highest example? And is it wrong to give examples without mentioning it?

It is not obligatory for a Muslim to say "and to Allah belongs the highest example" when giving any example, but it is recommended if an example of a creature is compared to an example of Allah Almighty, out of glorification and to absolve Allah of the attributes of creatures.

Scholars have used this phrase to indicate that Allah possesses the highest attribute and absolute perfection, such as the saying of Allah the Almighty: "For those who do not believe in the Hereafter is the worst attributes; and to Allah belongs the highest attribute. And He is the Exalted in Might, the Wise."

The "highest example" is the supreme description that is not subject to modification and does not resemble anything, and the "lam" (لِ) in it denotes entitlement.
