In the name of Allah (God), The Creator of everything, Who alone knows what is good and bad for His creation.
For whatever is sound and correct, all praise is due to Allah; any errors are due to human fallibility.
Al-Islam is a divinely-revealed, perfect and complete way of life immaculately conveyed by Muhammad, the last of the Prophets and Messengers (peace be upon them all) sent to the whole of humanity until the Last Day. It is therefore the only valid system; consequently, any other way of life is invalid and false. Furthermore, its sources are permanently protected by Allah Himself. Therefore, Islam is not in any need of reformation whatsoever and cannot be reformed by anybody either.
Currently, the enemies of Islam are trying to pressurise the Muslims to undergo a reformation akin to the one Christian Europe underwent a few centuries ago. They wrongly claim that the declined situation of the Muslims is because of their attachment to Islam and all its laws. These secularists, led by the USA, only acknowledge Islam as a spiritual creed - a religion comprising belief in God, Judgement Day, Heaven and Hell, rituals, morals and dietary rules. They reject it as a political creed - a (deeply-rooted) belief about human existence in the universe from which a comprehensive system (branches) governing societal relationships. They doubt the validity of Islam because it came about 14 centuries ago and call it backward and, yet, they embrace something pre-dating it, i.e. Democracy.
The hypocrisy doesn't stop there. Muslims are told that Democracy doesn't contradict Islam and that it is the way forward!
Through carefully-chosen words, Muslims are targets of a sinister campaign of deception aimed at getting them to accept changes to their belief in those laws which contradict the Western Freedoms. This is quite evident in those countries described as being part of the 'Arab Spring' in which, under slogans such as 'revolution' and 'reform', America is backing 'Moderate Islam' as opposed to 'Extremist Islam' - these are invalid terms coined by Westerners who judge by false criteria.

The punishment of death for apostasy and (by stoning for) adultery are but 2 examples of Islamic law over which Muslims cannot differ. Others include the obligation to have one khalifah/imam for all Muslims, living borderlessly and striving militarily to liberate the rest of humanity from the oppression resulting from being ruled by other than God's law. It is those very greedy oppressors who fear the loss of their positions and are attempting to dupe Muslims into angering Allah by submitting to other than Him.
All solutions to all problems for all people, times and places exist already. Therefore, there is no cause for any legislation whatsoever for, as already stated, Islam is in no need of reformation - it is divinely perfected and completed. Muslims interpret and implement, they don't - because nobody can - legislate. As a result, the presence of a legislature is invalid; the only valid bodies in Islam are the executive and the judiciary.
To conclude, there is no human liberation except by embracing Islam both credally and legally, i.e. the reformation of people by them believing in the creed of Islam and worshipping Allah alone. Any attempt to reform Islam is futile. Islam reforms people - it cannot be reformed by them.
