How does one search for an issue and its evidence in terms of drawing inferences in Islamic law?

The process of researching a jurisprudential issue begins by examining the core texts of fiqh related to the matter. If no specific text from early scholars is found with its evidence, then one should consult the core texts of hadith and their commentaries, as well as the verses of legal rulings (ayat al-ahkam) and their interpretations. Following this, consideration should be given to the objectives of Sharia (Maqasid al-Sharia), its general principles, and the fatwas of scholars that are based on achieving benefits and averting harms. This process requires an experienced researcher, as it involves a form of analogical deduction (qiyas), along with the necessity of seeking assistance from scholars and students of knowledge.
