Facebook Messenger without permissions Facebook Messenger for Android requires a lot of permissions - like reading my SMS and other stuff. I really don't like that. Is there any fb chat application which doesn't require such permissions?  

In fact i would only need a notification when there is a new message.
You can use ChatSecure (formerly known as “Gibberbot”) with Facebook added as an XMPP account. Just enter username@facebook.com and your Facebook password to connect. 

For even more protection of your details you can use the "Connect via Tor" option with Orbot (the Android port of Tor) to hide your location from Facebook as well.
