The only prerequisite for Dream is that you need to be able to read the Quran in Arabic fluently, even if you cannot write in Arabic. If you can read Arabic with some degree of flow but without any comprehension, this course will suit you.
If you cannot read the Quran at all, we recommend checking out Bayyinah TV which has many Arabic lessons available completely online. It has an Arabic journey which starts at the very beginning for those who have no Arabic knowledge. For more information, please visit bayyinahtv.com
