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 excellent book for non-Muslims explaining various aspects of Islam.

In the religion of Islam after declaring the shahadah, the second most important pillar is the Salaah (prayer). Whenever the messenger of Allah (peace be upon him) used to pray, He used to raise both his hands up to his ears or shoulders during the first takbeer, before ruku’ and after ruku, as is proven from the Mutawaatir ahadith. In common language, it is called “Rafa Yadain”.
