I believe the ayah as how it is. If Allah says he has a shin then he does. Just like in other ayahs he mentions his hands, eyes, and in another hadeeth he mentions that he will put his foot into hell when hell keeps asking for more people. But even though he says all this, we cannot compare these features to ours, because Allah also says that there is nothing like Him.

This is from what I learned
Allahu A'lam
