Glyphs is a great piece of software for beginners and very reasonably priced (I believe less than half the price of FontLab Studio). The interface is much easier to get to grips with and is much more "app-like". If you're a beginner in font design I would without a doubt recommend Glyphs over FontLab.
For most beginners Glyphs Mini (which is a scaled back version of Glyphs and a fifth of the price!) is more than enough, but Glyphs Mini only supports simple scripts and not Arabic, so that may mean you want to go straight for the full version. You can however upgrade from from Mini to the full version for a reduced rate.
FontLab does have some features that aren't available in Glyphs like the autotrace feature. Broadly speaking though there isn't a huge difference in features—especially for someone starting out with font design.
In short—go with Glyphs. 100%.
