Islam makes clear what is beneficial and what is harmful to the individual, to the family, and to the society as a whole. The criterion is both a guide and a reference. It is government for the individual, government for the family, government for the community and government for the nation. Because in Islam, the believers recognize the Almighty Creator as the Sovereign Ruler, the Cherisher and Provider who has given us laws for our guidance, there is no change in the law when there is a change in the administration as long as the administration follows the Sharia. Man is fallible.
Man is unreliable.
Man succumbs to pressure. The Creator is high above all those human weaknesses. He it is Who causes the night to follow the day and the day to follow the night. He brings the change of seasons, all according to his design and Wisdom. He created the Sun and the Moon and set them in orbit according to His command, and by the accuracy of their movement, mankind has kept the measure of time.
