I've been reading this book called "Heaven's Bankers: Inside the Hidden World of Islamic Finance" by Harris Irfan and it's been great so far. I'm about halfway through the book. I highly recommend it. Here is the Amazon link:

It’s the yellow one with the W in the middle.

If that doesn’t work for whatever reason, just use my invite code it’ll redirect you to it thru the play store. https://wealthsimple.com/invite/FPC8WG
