Ijma'
إجماع
Pronunciation: ij-MAH
Scholarly consensus: a ruling on which qualified jurists of an era have all agreed, making it binding.
Definition
The unanimous agreement of qualified Muslim jurists of a given period on a point of law, recognized as the third source of Islamic law after the Qur'an and Sunnah. Where ijma' exists, the ruling is settled and later scholars may not reopen it.
Genuine ijma' is rare and is claimed carefully; many financial rulings described as consensus are actually majority positions. The prohibition of interest on loans (riba al-nasi'ah) and of gambling are examples of true consensus, while the status of conventional insurance, 0% financing, and stock screening thresholds are contested.
How Ijma' Works in Practice
Knowing which financial rulings rest on ijma' and which do not is the key to reading fatwas and marketing claims correctly. On the consensus side: lending money at interest is prohibited; receiving interest is prohibited; gambling is prohibited; a sale requires the seller to own what is sold; and a deferred price may exceed a spot price in a genuine sale. Those rulings are not open for debate and any product that contradicts them is not made permissible by a certificate.
On the majority-but-not-consensus side sit most of the questions that generate controversy in U.S. halal finance: whether conventional insurance is prohibited or tolerated by need (majority prohibit; a significant minority permit), whether late-payment penalties directed to charity are valid (majority permit with conditions), what debt ratio a company may carry before its stock is impermissible (30%, 33%, or none, depending on the methodology), whether zakat is due on retirement accounts you cannot access without penalty, and whether cryptocurrency is money, a commodity, or impermissible. When a provider or a critic says 'scholars agree' about one of these, they are describing a majority or their own board's view, not ijma'. The practical rule for a consumer: treat consensus rulings as non-negotiable, and on contested questions pick a qualified position, apply it consistently, and do not condemn those who follow another.
HalalWallet's contested-questions guides lay out each position with its holders for exactly this reason.
