Common reasons the picture gets blurred.

Blur is movement. Anything related to the picture taking process that introduces or highlights movement will result to blur. The common causes of blur are the following.

1. The subject moved.
2. You moved or the camera moved.
3. Shutter speed is slow allowing more time for movement to show.
4. You are shooting in the dark. (Classic!) This forces the camera to use a slow shutter speed.

To avoid blur, shoot under lots of light and use a fast shutter speed.
