It is required in Islam to pay the zakat and other obligations towards the leader of the Muslims, for this a registry of Muslims is essential was such a registry maintained by the Muslims of the time? and does it help to have a global database of Muslims around the world for better management and utilization of Muslim resources?
There is a major Shia Islamic sect which makes it compulsory to have a unique ID cards for its adherents and I see them using it to profile its adherents and manage the human resources in an efficient way. All their religious activities, payments etc are logged in a global database. Is this a correct thing to do?
