Do Salafis take literal meaning of the Quran?

I didn't mention anything about the Messenger(SAW) or Qura'n so please don't try to put your words in my mouth.

In Qura'n Allah said:

31:27. And if all the trees on earth were pens and the ocean (were ink), with seven oceans behind it to add to its (supply), yet would not the words of Allah be exhausted (in the writing): for Allah is Exalted in Power, full of Wisdom.

Do you think you can completely uderstand Allah, if yes then please enlighten us with your wisdom???
