I really wish I get a pdf copy to read this book in English.

The abriged version is small but good.

In English, you can get the abridged version here: http://archive.org/details/KitabAlRu...ry-IbnAlQayyim

If you want the listen to the detailed explanation on this topic, I would suggest Watching Shaykh Hasan Ali's talk on this topic: http://www.youtube.com/watch?v=gAhgITGEObI
