Two years back (wow time flies), we conducted an interview with the co-author of KnowInterst.
Recently, we’ve learned that the family, mashaAllah tabarakaAllah, is about to pay off their house using their pure installment method (as described in their book KnowInterest).
They approached HalalBuzz (our marketing service) to help them promote their ebook so they can pay off the outstanding balance, inshaAllah.
So, if you like to know how they bought their house interest free you can buy their ebook at http://knowInterest.com.
We also urge you to spread the word to support the concept of Halal economy and help families own their homes without Riba.
May Allah reward you and bless your family
