Public interest; a basis of law. According to necessity and particular circumstances, it consists of prohibiting or permitting something on the basis of whether or not it serves the public's benefit or welfare. The concept of public interest can be very helpful in cases not regulated by the Quran, Sunnah, or qiyas (analogy). Here, equitable considerations can override the results of strict analogy, taking into account the public's welfare. Shafiis do not allow juridical opinions based on maslahah.
