Have a community pharmacy at the masjid.
Many times I drive and go through the prep to pray at the masjid only to spend 10 minutes or so. I can’t help it, I just pray and head out to run errands. I’d love to have other day-to-day suppliers/shops so I can do many things all the time.
This includes the pharmacy, the grocery store, the dry cleaning, etc. Not only does it allow people to spend more time together but also creates sustainability for the masjid.
Lastly, would love to see things like darts and chai after salah to simply hang out INSIDE the masjid.
