I must agree mashallah, he recharges my batteries and provides alot of answers to non muslims and new muslims alike. My brother who is also a convert (not too practical though) make dua for him, recently was playing the tape and one of his friends popped by and he listened too and then at the end of the tape he repeated the shahaada, although my brother doesn't know how serious he was but he says he said did you hear me, i'm a muslim now. Allah alone knows if he truly understood and accepted from his heart but it could lead to his salvation if he is sincere.Allah knows best!
