The Correct Path to Establishing the Law of Allah on Earth

Question:
Your Eminence the Shaykh (may Allah preserve him). Muslims in many Muslim lands have been afflicted by the implementation of man-made laws and the separation of the Islamic Shari'ah by their rulers and the ruled. Much corruption has appeared, including shirk (associating partners with Allah), kufr (disbelief), fisq (open sinfulness), and other wrongs. The Muslim youth in their lands are in confusion; some see that the matter requires reforming the head so that the body is reformed, while others see that the matter begins with reforming the individual so that society is reformed, and then the leadership becomes righteous. What is Your Eminence's advice to these and those? And what is the correct path that every Muslim should strive to follow to achieve the law of Allah on earth and remove these wrongs and much corruption?

Answer:
The advice is that the community must fear Allah, strive to be upright in the command of Allah, cooperate with their brothers in taqwa (mindfulness of Allah), assist the state in what is good and in accordance with the Shari'ah, and oppose it in what contradicts the Shari'ah. They should pressure it in what contradicts the Shari'ah according to their capacity and ability. When they are upright in themselves and cooperate in good, the state will be free of that, return to the right path, and fear them. Likewise, if they cooperate in righteousness and taqwa and become a majority with strength, they will be able to subject the state to the truth or remove it, because they have strength that others do not have.
As long as the state is stronger than them, they must strive in obedience to Allah, ask Allah for its guidance, assist it in good, and advise it, whether high or low, until it inclines to the truth and agrees to the truth. This is the straight path. As for rising up in prayer and a night of obedience, this increases corruption and increases evil, and no benefit is achieved for the Muslims through it. Yes.
But the sound method is that you, O servant of Allah, and your good brothers, strive in obedience to Allah and His Messenger, in upholding the command of Allah, and in advising people and directing them to good until people are upright in good. When people turn to good, the leaders will submit to good, incline to good, rule by the Shari'ah, and be upright. Or, if the Muslims increase in number, they will seize the matter from them, and Allah will assist them against them. If this does not happen and this is not sought, seek another land, move to another land, and emigrate to another land where you will find spaciousness and good, no matter how you assess the affairs of the Muslims.
