A summary of the concepts held by the Ahl al-Sunnah. The Constitution. A constitution is the fundamental law or basic statute of any country. It is the ultimate authority to which all other laws must refer. For this reason, it is often called the "mother of laws." In democratic systems, it may be amended or abolished. This requires a public referendum. In man-made systems, a ruler may also suspend it. This occurs when he rules according to what they call emergency law. The constitution of the Muslims is the Book of Allah and the Sunnah. They are the two authorities that govern the legal system in Islam. Any subsidiary law must be referred back to them. If Muslims in any country draft a constitution organized into primary articles, then its first and most fundamental article should be— one that cannot be abolished, amended, or subjected to a referendum— that the Islamic Shari'ah is the sole source of legislation, which invalidates any legislation that contradicts it. This article must be practically implemented on the ground, not merely stated as a way to throw dust in people's eyes, or phrased in cunning, evasive language. Some might, for instance, remove the definite article "the" from the word "source," to make it merely one source among many, rather than the sole source. With this aforementioned criterion, any constitution of an Islamic country becomes a branch derived from the Book of Allah and the Sunnah, governed by them, and incapable of contradicting them.
