Difference between a Promise and a Contract

The distinction between a promise and a contract has vast implications for Islamic finance in the contemporary era (especially in murabahah financing) as we will explore later.

Kahrofa describes a promise as a verbal proposition made by one party to undertake something to the benefit of the other. Note the absence here of an explicit ijaab and qabool. Taqi Usmani further explains a promise as a one-sided commitment as opposed to a contract which typically requires two sides (with the exception of unilateral contracts that are rare in nature).

Kharofa explains that a contract has to be executed both from the legal and moral point-of-view, whereas a promise implies only a moral duty. Kharofa argues that fulfilling a promise is not an obligation (wajib), however, it is a noble quality. This view is particularly ascribed to Imam Abu Hanifah, Imam Shafi’e and Imam Ahmad.

Both Kharofa and Taqi Usmani point out that a promise is enforceable in the court under certain circumstances in accordance with the views held by Hasan al-Basri, Sa’id bin al-Ashwa, Imam Bukhari, Ibn al-‘Arabi, al-Ghazali to name a few. This implies that a promise is legally enforceable.

Taqi Usmani argues that circumstances in the modern economy necessitate that a promise, for the purposes of Islamic commercial law, be considered binding.

We will not go into the details of the proofs provided for each of these positions as they are available on the Internet in Taqi Usmani’s book (referenced below). For our purposes what is important to understand is that promises are considered binding in Islamic commercial law by the majority of the contemporary scholars with the following conditions:

  1. it should be a one-sided promise;
  2. the promise must have caused the promisor to incur some liability;
  3. If the promise is to purchase something, the actual sale must take place at the appointed time by the exchange of offer and acceptance. Mere promise itself should not be taken as the concluded sale; and
  4. If the promisor backs out of his promise, the court may force him either to purchase the commodity or pay actual damages to the seller. The actual damages will include the actual monetary loss suffered by him, but will not include the opportunity cost.
