Not Known says that: I have got several suggestions. (1) To develop and present Islamic perspective of Science to the world. (2) To develop and present Islamic economics to the world. (3) To present Islam itself along the lines of Maulana Rehmatullah Kairanvi (RA), Shaikh Deedat (RA) and Dr Zakir Naik. (4) To develop and present the Islamic perspective on social and cultural issues to the world. (Just see Ramchandra Guha's flippancy here. I'll, IA, augment that post with my own perspective.) (5) To develop and present the Islamic perspective on Psychology to the world. This one might be the easiest one and most effective one because spiritual and tasawwuf investigations of Muslims have no parallel. (6) To translate the history, specially of Indian subcontinent, as presented by our scholars, to the world. (7) Suggest other possible effective Islamic institutions that Ummah can build. And except for Dawah most of them can be done on keyboard itself! Wassalam PS: Post is used here also.
