the book is a propoganda. there is no "liberal" islam. islam is one and complete(plz ignore the shiites).no head covering! it is teaching muslims not islam but western atheist culture
Sunni/shiite are not madhabs, ok, the shia issue is very very controversial, some of them are considered kafirs. And please don't consider this hate, cause its not, when people start practicing shirk and idolatory and call themselves muslims, what will happen to the manhaj.
Don't you think we should protect the real identity of Islam, I mean what will happen when people start inventing new sects and start calling it Islam, isn't that the main concern, "hifth al deen".
