According to search-discovered classical Islamic scholarship, the ruling on witnessing in financial transactions, detailed in Quran 2:282, is a foundational principle of Islamic contract law. Ibn Kathir explains this verse, the longest in the Quran, establishes a divine mandate for documenting debts to prevent disputes. The primary requirement is for two male witnesses. However, if two men are not available, the verse specifies an alternative of one man and two women. Al-Qurtubi clarifies the wisdom behind this alternative, which is explicitly stated in the verse itself: "so that if one of the two women should err (through forgetfulness), the other can remind her." This is understood not as a statement on a woman's general capacity, but as a practical safeguard in commercial matters where, historically, women had less direct engagement. Contemporary scholars like Dr. Shabir Ally emphasize that this ruling is context-specific to financial attestation and does not apply to all forms of testimony in Islam, where a woman's witness can be equal or even exclusively required.
