Perfection is for God. Simple. If he is not perfect, he cannot be God.
And nobody else can be perfect, because then they all would be God.
But excellence is for all of us human beings.
As a result, to be born human and not to seek excellence, and not to engage in the deliberate and unremitting pursuit of excellence in everything we do, is to turn our back on God.
Now go and read the Hadith Sharif on something called Itqaan.
I recall the words: "An Yutqinahu!"
Am I right?
