Modern Islamic banking arose to fulfill Muslim demands for financial services free from riba (usury or interest), which is explicitly prohibited in the Qur’an (Qur’an 2:275–279). Institutions like Pakistan’s Meezan Bank offer products structured to avoid a direct interest charge, using sale, lease, or partnership contracts instead of conventional loans. However, Islamic finance has been dogged by criticism that it sometimes merely re-labels interest-bearing loans in legalistic ways – achieving the same result as conventional finance while claiming Sharī‘ah compliance. This issue has raised the question of form versus substance: do these Islamic products genuinely uphold the spirit of the Sharī‘ah, or do they resemble the “Sabbath” ruse of bygone communities who observed the letter of the law but betrayed its intent? The “Sabbath Pond Test” is a metaphor we adopt from the Quranic account in Surah Al-A‘raf (7:163-166). In that narrative, a community of Banu Israel was forbidden to fish on the Sabbath, yet they laid out nets the day before to catch fish by subterfuge. They were technically avoiding “fishing” on the holy day, but in reality they enjoyed its fruits – an act of divine disobedience that earned severe punishment (Qur’an 7:163–166; 2:65; 7:166). This parable warns against clever legal stratagems (ḥiyal) that violate the spirit of a law while keeping its letter. By analogy, if Islamic banks only superficially replace the word “interest” with “profit” or “rent” without altering the exploitative or risk-free nature of the transaction, they may be repeating the error of the Sabbath-breakers.
