The other areas inadequately dealt with include: aradi (land), anfal (use of natural resources), jihad, qadawat (adjudication), hudud, qisas, ta`zirat, civil rights, economic and social affairs, etc. It is to be hoped that the `ulama' will fill this vacuum as early as possible. Legal Deduction from the Qur'an: The most authentic of all the sources for identifying the Divine laws is the Holy Qur'an.
With regard to this fact, there is no difference of opinion whatever between Shi'i and Sunni scholars. However, in making use of this great and everlasting source, it is essential that one should have knowledge of certain prerequisite matters. Without the knowledge of these prerequisites, an effort to infer ahkam from the Qur'an will neither be productive nor indicative of correct judgement.
For properly inferring the Divine ahkam from the Qur'an, there exist certain criteria and standards, for the Qur'an has certainly entrusted mankind with the framework for answering all the legal and legislative needs of man until the Judgement's Day. Evidently, one cannot expect to find a detailed and elaborate description of the ahkam in some five hundred verses. Thus, in the Qur'anic verses we find mostly the general basic principles, which are susceptible to the derivation of particular laws.
Furthermore, in many instances, it is possible to adjudge matters on the basis of an all-inclusive consideration of the Qur'anic statements of a general or specific nature, as well as its nusus and zawahir. For this very reason, deduction of a hukrn from the Qur'an requires expertise in usul and jurisprudential principles, and any novice unfamiliar with the subtleties of the revelation can hardly be expected to possess the power of deduction of the ahkam of the Shari'ah from the Qur'an.
On the other hand, it is these criteria and standards, as well as the degree of the understanding of scholars of them, that have given rise to differences among the Islamic sects in regard to the deduction of the ahkam. Amir al-Mu'minin `Ali (A) has given a statement in this regard.
He says: On this basis, the inference of the Divine ahkam, the laws of the Shari'ah, and Islamic values presuppose sufficient knowledge of these kind of subtleties, nuances, specifics and particulars required for investigation and research into the meaning and significance of the Qur'anic verses.
