There is a wide collection of Arabic language learning books.
The best place to find definitions of Arabic words in Arabic is in an Arabic dictionary, either in book form or online.
Like any language, the best way to learn is by immersion. If that opportunity does not exist for you, I recommend finding an Arab student at one of your local colleges to tutor you. Another option would be to use a software/e-book package that provides an interactive multimedia learning experience. There are some good Arabic books available on the Arabic store website (see related link) the best one for you would probably be the Gateway to Arabic Series because it contains full translation. The most popular book is Kitabul Assasi and is used in many language institutes in the Middle East that foreign students visit. Another great program to learn Arabic is through RosettaStone. Please see the related links for websites that could help you learn Arabic. See related links for great sites to learn Arabic. Or you could buy Rosetta Stone to learn Arabic. Online classes - Arabic College (link below) - you will learn Arabic in the most effective way. They teach Arabic in Live Video Interactive Classes, with a native Arabic teacher who are available 24 hours a day, 7 days a week, no fixed pace and no fixed schedule.
The last heavenly book, the holy Qur'an, was revealed to the Last Prophet Hazrat Muhammad SAW in Arabic language. The Muslims are required to recite Arabic to learn and understand it.
The best book is the holy Quran. Also, if you want to learn about the prophets what so ever, you should buy DVDs. They'll let you learn more. But, if you don't know Arabic, there are websites that write it in English that will help you pronounce the words like qurantranslitteration.com
