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.
A very important book talks about some misconceptions about Islam such as: allowing husbands to beat their wives, punishments by Islam for the criminals, not allowing religious freedom which is considered intolerance, prohibiting music, and terrorism in the name of jihad.
A very useful article shows the pure Islamic belief of monotheism. It briefly mentions that Allah alone is worthy of worship, He is worshipped directly and Allah is not like his creation nor his creation is like him.
