assalam alaykum

Im confused. Are there really such things as "saints" in Islam? I was reading about a place in Alexandria, Egypt where a saint is buried underneath a mosque there. (at least I think it's under a mosque). Anyways, I also watched a program about Iran last week and they showed a lot of people going to various sites there where saints are buried and kissing the tombs, etc.

What's up with that? One of the things that attracted me to Islam was the fact that they don't have statues and like a million saints, etc. to pray to like I did when I was Catholic. The simplicity of praying to one God, Allah was the main draw for me so when I see stuff like this it is depressing and confusing.

help.
