Having a lot of vocabulary in learning English as a foreign language is one of the keys to get confident in conveying the message either in the written or in the spoken forms. This study aimed at designing an Islamic vocabulary book for English students at Islamic University and finding out the influence of using Islamic vocabulary book to improve English students’ vocabulary.
