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.

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."

Iqtidaa-ul-‘Ilm al-‘Amal By Al-Khateeb Al-Baghdaadee. This is the second book in the "Classical Knowledge Series", which is a collection of selected scholarly works from the past that deal with the subject of religious knowledge. The first book in this blessed series was “The Book of Knowledge” written by Imaam Abu Khaithamah Zuhayr bin Harb An-Nasaa’ee (Died 234H), may Allah have mercy on him. Since that book served as an introduction to knowledge, its virtues, merits and manners, it seemed proper that the second book be dedicated to the next level of knowledge, which is its result and outcome, and that is righteous deeds. And what better work to present on this subject than the classic and well-known treatise of the distinguished Imaam, Al-Khateeb Al-Baghdaadee, 'Iqtidaa-ul-‘Ilm al-‘Amal' (Knowledge Mandates Action).
