Introduction to Bay’ al-Istisna

Abstract

This article delves into the concept of Bay’ al-Istisna (Manufacturing Sale) by examining its linguistic and technical definitions, legal standing, and its acceptance within Islamic jurisprudence. The research highlights key aspects related to this unique mode of sale and aims to clarify its application in light of Islamic principles and customary practices (‘urf).
At the core of the study lies the exploration of the terms Bay’ and Istisna. Bay’, which signifies "sale," is analyzed both linguistically and terminologically to establish its foundational meaning. Similarly, Istisna, meaning "manufacturing upon order," is examined in detail to determine whether it constitutes a binding contract or simply a promise. To substantiate the permissibility of Bay’ al-Istisna, evidence is drawn from the sayings of the Prophet Muhammad (peace be upon him), ensuring the discussion aligns with established Islamic traditions.
A significant part of the research is dedicated to understanding the role of ‘urf (custom) in validating Bay’ al-Istisna. The linguistic and technical definitions of ‘urf are explained, along with its classifications into general (‘urf ‘aam) and specific (‘urf khaas). The study underscores the importance of ‘urf in Islamic law, particularly its influence on the recognition and acceptance of practices like Bay’ al-Istisna.
Furthermore, the article addresses the differences of opinion among Islamic schools of thought regarding the permissibility of Bay’ al-Istisna. The research brings to light the diverse views of scholars and jurists, providing a comprehensive overview of the debate. Despite these differences, the findings reveal a consensus that Bay’ al-Istisna is a legitimate and permissible form of sale under Islamic law. This permissibility is rooted in the recognition of valid customary practices and the absence of any explicit prohibitions in the Shari’ah.
