The authority of delegated interest and its applications in financial transactions

In Islamic jurisprudence, the principle of maslahah plays an important role in ensuring the welfare of Muslims in this world and the hereafter. Maslahah refers to the pursuit of benefits and the avoidance of harm in life. However, not all social issues have clear texts from the Qur'an or Hadith. This is where the concept of maslahah mursalah emerges as a relevant approach to solving contemporary problems that are not directly mentioned in the primary sources of Islam. Maslahah mursalah refers to benefits that are not mentioned in the text but are acceptable based on rational considerations that benefit the general public. The history of the acceptance of maslaha mursala in Islamic jurisprudence can be traced back to the early ages, when scholars began to use this method to solve problems that had no clear solution in the Qur'an and Hadith. It is an important method for overcoming issues that arise in Islamic society, especially in the field of transactions such as economics, business, and social affairs. For example, Islamic scholars use maslaha mursala in determining insurance law or modern financial products, which are not It existed at the time of the Prophet but was accepted on the basis of the public interest, which brings benefits and averts harm. The importance of the public interest in Islam lies not only in its ability to provide solutions to contemporary problems, but also in its role in preserving justice and the welfare of Muslims as a whole. This principle is not limited to resolving issues that have no written text but also plays a role in strengthening the Islamic jurisprudence system, which is flexible and adaptable to changes over time. In this paper, we will discuss in more detail the definition of maslaha mursala, its importance in transactions, and the application of this principle in resolving modern issues facing Muslim society.
