The authority of consensus and its applications in high-level transactions

In the study of Islamic jurisprudence, understanding the sources of reference is crucial to ensuring that practices and decisions are based on correct legal principles. In this context, there are four main sources that are considered references in the development of Islamic jurisprudence: the Holy Quran, the Sunnah, consensus, and analogy. The importance of reference sources in Islam is that these sources form the basis of Islamic legislation and provide moral guidance and guidance for Muslims. The Holy Quran is considered the main source of revelation from Allah, followed by the Sunnah, which clarifies and complements the teachings of the Quran through practical examples from the life of Prophet Muhammad, peace be upon him. Consensus, as the third source, plays an important role in determining agreement among scholars on issues not directly mentioned in the Quran or Sunnah. This shows that Islamic jurisprudence is not static, but can adapt to developments over time and social contexts. Qiyas, or analogy, also allows scholars to apply existing legal principles to new cases based on similarities in causes (Fahmi, 2013).

It must be ensured that the sources of Islamic thought come from revelation that is definitive (categorical). This is because if these sources are questionable, it will open the door to disagreement and confusion in understanding the teachings of religion. Allah, the Exalted, said in the Qur'an “And do not pursue that of which you have no knowledge” (Al-Isra: 36)
