In a previous post I mentioned that I would have more information and pictures of the edition. Dar al-Minhaj has no information about this edition on their website. In fact I fear that the website has not been updated in some time. At any rate this is an important edition that deserves a close look.
As you can see in the photo, the books are about 17.5 x 24.5 cm.
The list of distributors is available on their website. There are no distributors in the United States. As of this writing, the UK distributor does not have this book. Dandees bookshop in Amman, Jordan has them. Needless to say the bookstores in Jeddah have it. Alternatively, you may write the publisher directly: info at alminhaj dot com. They are responsive and will email you back.
