Terry,
What I'm saying is, a lot of commands found in the Bible (and I assume also in the Quran) may seem like petty concerns. The gentleman in question seems to be saying that, if something seems petty, then God must not care about it.
Scriptural arguments aside, how is anything too small for God to notice or care about? It's not as if He only has the time or mental capacity to care about the really big stuff. He's God, right?
It's like the argument that, if there is a God, he's obviously not concerned with a few backward little creatures on some unremarkable planet. It might be a realistic argument, if God were as limited, or as uncaring as we are.
