It's a good story that he said that. That's often attributed to Ali, but if you compare it in style and form to his other quotes, it sounds kinda fake. The dissenting opinion is, that "quote" was created by Adidas for an ad campaign.
Here's the entire quote from the commercial. Video from that time doesn't show Ali saying it - only the narrator:

Impossible is not a fact. It's an opinion.
Impossible is not a declaration. It's a dare.
Impossible is potential.
Impossible is temporary.
Impossible is nothing.
