What are the best suggested materials (a book or two, a recorded tape or two, a video tape or two) for introducing non-Muslims to Islam, taking into consideration that the materials should be engaging, concise, and simple?

For non-Muslims, the following books are recommended: "How to Enter Islam" by Muhammad Sulaiman Al-Ashqar, and "Don't Be Sad" by Sheikh Aidh Al-Qarni. Among audio cassettes, "An Invitation to Contemplate" by Sheikh Ali Al-Qarni is recommended. As for video cassettes, "It is the Truth" by Sheikh Abd Al-Majid Al-Zindani, and "Ahmed Deedat's Debates" by Sheikh Ahmed Deedat are recommended.
