If you ever plan to play a Muslim ruler than absolutely. I wrote a short review of it for Voigtkampf's site but allow me to sum up as best I can. SoI is essentially an expansion pack that splits CK2 into two very different but very fun worlds of gameplay. Playing Muslim is completely different than playing Christian with that DLC and is all sorts of fun. $2.50 is an unthinkably good deal for everything you're getting.

If you never plan to play on that side of the map, however, then feel free to ignore it.
