Government is about governing roads, infrastructure, health, welfare, science, taxation, education.
I dont understand the need of putting an Alim in for e.g. the department of civil and urban engineering.
If you dont want an Alim for that role then why do you say you are for a government of people learned in 'sharia'?
People talk illogical things. People say they want sharia-based government. But however not a single government on earth has Alims in its parliaments because logic dictates that Alims should advise on religious affairs to population not sit as a chairman of the ministry of health and advise governments how to make hospitals be efficient or of higher quality.
Parliament, democracy, secularism and a constitution not contradicting Islamic values all facilitate governance. They are not meant to replace religion or overstep it. They are doing what they are supposed to do i.e. Govern the sophistications of modern civilization. Sometimes I wonder how muslims can sit and keep on repeating the mantra 'sharia' government and dont know how the hell to go about it or have no model example in modern times to exemplify it. Every other government which says we are 'sharia based' is rejected by people who want sharia based government because they are too ashamed to say that society is a product of sharia because all examples so far are a mess and shambles.
