Impossibility.

إِنَّمَا أَمْرُهُ إِذَا أَرَادَ شَيْئًا أَنْ يَقُولَ لَهُ كُنْ فَيَكُونُ

Verily, when He intends a thing, His command is, "Be", and it is!

(Yaasin: Verse 82)

Kun fayakun.

Be--and it is.

No need for lengthy spoken sermons or written paragraphs. Two words--that's all it takes.

Two words to explain God's absolute power over everything that exists. Short, to the point and perfect. Two words that, when one reads between the lines, is one way of saying that nothing is impossible.

A very popular sports brand adopts a clever twist of that phrase as a tagline: Impossible is nothing. 

Now, the million-dollar question is: If nothing is impossible, then why does the word impossible even exist?

Why do we need to conceive the idea of impossibility when we know for sure that anything and everything is possible? Why can't it be just "possible" without the "im-"?  Why make things complicated?

Human nature, perhaps?
