In the Summer of 2010, Sheikh Jamal Ben Ameur, gave a Fiqh of Dawah class in Masjed At-Tawbah in Maple Grove. Here are the lectures if you would like to listen to them. There was much discussion and questions during the lecture. So, listen to them, but before you implement please consult Sh. Jamal himself or a scholar in your area–per request by Sh. Jamal himself.
