In order to remove religious differences amongst ourselves. -- especially shia, sunni. Don't you think we all should pray in common mosques/ Unified building. There should not be different mosques for Shias and Sunnis or for others.
That's how religious harmony will create and no suicide bomber or terrorist will be able to hit mosques at least because people of different sects. will be praying at one place. Moreover we will have a chance to know eachothers' believes and remove misconceptions.
