I ran into this interview of Faqih-ul-Asar Mufti Taqi Usmani saheb db about his efforts on Islamic Finance. The interview was done by Dharb-I-Mu'min.
I highly recommend reading the interview (if you haven't already done so). The interview gives us some appreciation of Mufti saheb db's (ongoing) struggle in establishing an Islamic Economic System.
A perfect Islamic system can not be created overnight, but it has to start somewhere. May Allah accept Mufti saheb db and other ulema's efforts in this regard and give us muslims a truly interest-free economic system.
Sorry for reposting it, if it has already been posted.
