Ushul Fiqh: The Reason Islamic Law Remains Relevant Through the Ages

A question often arises: ‘Islam has existed for more than 14 centuries. How can its laws still be relevant today?’ This query is particularly pertinent as we navigate the era of artificial intelligence (AI), digital transactions, e-wallets, and social media. Strangely, almost every new issue finds a legal discussion within Islam. One of the main reasons Islamic law keeps pace with the times is the science of ushul fiqh. This term may sound foreign to some, but its role is immense. Ushul fiqh is not a collection of halal and haram rules; rather, it is the science that teaches how those laws are established.

We often see people on social media casually declaring something ‘haram’ or ‘halal’ based on a single snippet of a verse or hadith. In reality, establishing a law in Islam is not that simple. There is a lengthy scholarly process involved, from understanding the meaning of a verse and examining the context of a hadith to studying the opinions of scholars and considering the objectives of Sharia. This is where the beauty of ushul fiqh lies. This science teaches that religion is not built on assumptions or emotions, but through a clear methodology. That is why Islamic law can answer new problems without having to change its primary sources, the Qur’an and Sunnah.

A simple example illustrates this. The Qur’an certainly never mentions QRIS, e-wallets, or artificial intelligence. However, this does not mean Islam lacks an answer. Scholars use the principles of ushul fiqh to assess whether a practice contains elements of riba (usury), gharar (excessive uncertainty), fraud, or whether it brings maslahah (public benefit). Thus, what changes is the object of the problem, while the legal principles remain firmly anchored in Sharia.

The biggest challenge today is not a shortage of Islamic law, but rather the way we understand it. In the age of social media, information spreads in seconds. One-minute sermon clips are often considered sufficient to answer complex issues. As a result, the discussion space is filled with debates that prioritise who speaks the loudest over who has the strongest argument. Ushul fiqh teaches something crucial: caution before concluding a ruling. This science also reminds us that a difference of opinion does not always mean one party is astray. In Islamic history, great scholars often held differing views because their methods of ijtihad (independent legal reasoning) were not always the same. These differences are proof that Islam possesses a rich intellectual tradition.

For the younger generation, understanding ushul fiqh is a vital tool to avoid easily believing every viral piece of religious content. Not everything that is popular on social media has a strong scholarly basis. By learning how ushul fiqh works, we become more critical, wiser, and less hasty in judging an issue. Ultimately, ushul fiqh is proof that Islam is not a religion left behind by the times. As long as humans continue to face new problems, ushul fiqh will serve as a bridge between the values of revelation and the reality of life. This is what keeps Islamic law ‘connected’ to the present day—not because it follows trends, but because it has a methodology capable of responding to change without losing its fundamental principles. Perhaps it is time we not only ask, ‘What is the ruling?’ but also begin to ask, ‘How is that ruling established?’ From that question, we will understand that behind every decision in Islamic law lies a process of thinking that is scholarly, profound, and full of responsibility. And that is where ushul fiqh plays its part.
