Arabic (إيجاب) for offer; an essential element of a contract (aqd) in Islamic finance. It constitutes the declaration or a firm proposal that is meant to give rise to an obligation. At the contracting session (majlis al-aqd), the parties to a contract exchange ijab and a counter-declaration, i.e., acceptance (qubul). Ijab signifies the willingness of a party to deliver something (asset, usufruct, service, etc) in return for something else (cash, asset, etc).

It is synonymous with ardh (عرض).
