I believe Islam is superior. And will not be surpassed. So I believe that the law of God is much superior to man-made law.
Superior in what, savagery? Or love and peace? All of the great religions have some of both. And none could demonstrate to have the ultimate truth, the reason so many denominations and sects abound. There's also the exploitation and the false justifications, manipulation made in the name of religion. All of that is very human. None of those religions predate humans, who created them. Even monotheism is relatively recent and corresponds to the power concentration of certain human elites. And within monotheist movements, Islam is a recent development. Some legal codes may be more successful than others, but they're all human. None are of divine origin.
Allah is the only one to legislate
Then why does he need you? You're pretending to be him or his intermediary but he's not there to confirm it and powerless to act by himself, making your idea of an all powerful God implausible. Just like you're only another human, without access to divine powers or insight.
man legislating and playing God in Parliament
That's nonsense. There is no divine government and the agents of governments are always humans. Law codes are also from humans and for humans. How can they be "playing God" who is not there to show the way or run it anyway? You're the one claiming to be speaking and acting for "God". That's your own problem.
Allah created my tongue to speak. I don't have freedom to come here, because Allah created my feet to walk. So I walk, and I speak, and I look, and I hear according to what God says.
According to what you claim that a purported god would be saying, and justifications and texts written by humans. And if he exists, he decided that your tongue and feet were not for savagery and that your destiny is jail. If you really believe that this is also according to "his will", rather than evidence for the lack of his existence or power, it reminds me of ridiculous human stories from mythology, like those of Adam or Job, who were exploited and tricked and made to suffer for a mythological figure that is obviously anthropomorphic, created by humans too. With silly attributes like jealousy, deception, narcissism, etc. If you hear voices, it's a neurological psychiatric condition, there's nothing divine involved.
I don't deal with hypotheticals
The existence of your deity is a hypothetical. The false belief that human law codes and traditions have a divine origin is a falsified hypothesis. You're working with false assumptions, false premises. You're only dealing with hypotheticals. Except that you are twisting them as "divine law" and as absolutes, to dictate your irrational ideology and to impose your control. You do not want to hear, you are blind and deaf to reality.
I like to deal with reality.
This reality is now life in jail, unfortunately. Not for "God sending people to Choudary", but for Choudary himself actively organizing to go after them, to radicalize and recruit them for terrorism... And there was no divine intervention to help, just like the organization was only humans, because "God" was powerless, could not do it by themself, or did not want that, while Choudary failed to get it.
Or the goal was hate, chaos, persecution complex and revenge. Also very human, even if an expression of the lowest instincts. I know good Muslims. This is something else. Some parts of the article that are not quoted suggest that campaigns involved the harassment of others, rejecting the law of the country, the abuse of women, violating the freedom of others under false "freedom" pretenses and the inability to understand that Choudary's "freedom" stops where it violates the freedoms of others. And the abuse of freedoms allowed by democracy in attempt to fight democracy. But ultimately, the freedom of criminals can be affected, as it was in this case. Fortunately, because UK law is not sharia savagery, the culprit advocating for exemplary punishments for frivolous reasons, was not executed or maimed. Will they be thankful?
