As an AI language model, I don't have real-time information or access to specific locations. Events and activities can change over time, and it's best to check with the venue or relevant organization for the most up-to-date information.

If you're looking for information on Islamic events, you can try checking reliable sources like local mosques, Islamic cultural centers, or community organizations in your area. They usually have announcements or updates about upcoming events and activities.
