A decision taken in the interest of the public becomes

A decision taken in the interest of the public is called Istislah in Islamic jurisprudence. Istislah is a term that refers to the use of public interest as a basis for legal reasoning in situations where there is no clear guidance from the Qur'an or Sunnah. It involves making a decision that benefits society as a whole, even if it may not necessarily be explicitly mentioned in Islamic law. Ijtihad, on the other hand, is the process of making a legal decision by independent reasoning and interpretation of the Qur'an and Sunnah. Urf refers to customary practices that are widely accepted in a particular society, while Jihad refers to the struggle for the sake of Allah. In summary, Istislah is the Islamic legal concept that refers to making decisions in the interest of the public, even if it is not explicitly mentioned in Islamic law.
