An important book shows the corrupt belief of Shi’ites. The author said in the introduction, “I wrote this book for a number of reasons including: (1) The increased efforts of the Shi’ites to spread their ideology in the Muslim world. (2) The danger of this deviant sect poses on Islam. (3) The ignorance of many Muslims about the danger of this deviant sect. (4) The corrupt Aqeedah (belief system) of the Shi’ites, which includes polytheism, defamation of the Quran and defamation of the Companions of the Prophet, may Allah be pleased with them all. (5) Their extreme beliefs in relation to their imams."

These are three good books for learning Arabic Language for the non-native speakers. But we should pay your attention that they are for who has slightly good knowledge about Arabic and how to pronounce it. We don't claim that you can consider them as an alternative to a teacher but they are good step for who wants to be excellent at Arabic. With these books, there is an Arabic-English glossary confined to the words mentioned in these books, and the author shows in its introduction how to find any word.
