Abstract

This article discusses the role of fiqh knowledge in managing the muamalah process, including in the context of buying and selling. The business in the field of wooden furniture is really hot because this business is very promising and produces large profits. Especially in Bengkalis Regency, an area that is an island in Riau Province. Even though this area is small, it has a lot of natural wealth. For example, mining for oil, palm oil, and furniture materials, namely quality trees and wood to be used in making houses and other furniture materials. The method used in this research is descriptive qualitative using library research. In practice, not many furniture business processes apply Islamic principles in running the business. For example, illegal logging of forests is carried out, the impact of which is detrimental to residents. In fact, in Islam itself, all businesses carried out are prohibited from destroying the environment and harming other people for the sake of personal interests and some groups. For this reason, this research was carried out to analyze and review the extent of the wooden furniture business practices in Bengkalis based on Islamic fiqh, both the implementation and transactions of the furniture business carried out.

This kind of buying and selling occurs considering that the level of public interest, from young people to adults, they switch activities by playing this kind of game. Even though a fatwa has been issued from the MUI regarding such games being haram. However, people in Bengkalis consider this game to be just a normal game. The purpose of this research is to find out about forms of buying and selling that are haram carried out with the status of online games. The research carried out is classified as field study type research. Where it uses primary and secondary data sources. The analysis used in this research is to present qualitative analysis to describe and describe slot game transactions in Bengkalis Regency which are studied based on Islamic jurisprudence and law. The current practice of Game Chip trading transactions can be Web-based, starting from advertising on internet-based virtual entertainment, be it Facebook, Instagram, WA and other virtual applications. Thus, the practice of buying and selling slot games is that the object/goods traded contain a maysir component. According to the terms and conditions, buying and selling chips in online games violates Islamic law in buying and selling because it contains elements of gambling (maysir).
