Valid Sale: Offer, Acceptance, Subject and Price

A valid sale requires clear agreement through offer and acceptance, a lawful identifiable subject and a sufficiently known price. Ownership and deliverability also matter.

In Hanafi commercial law, a sale transfers ownership of a lawful, identifiable item for an agreed price. Offer and acceptance express contractual agreement. The subject must be capable of lawful sale and generally deliverable, while the price must be sufficiently known to avoid serious disputes. Consent obtained through deception is ethically defective, and ownership or authority to sell must be examined. A contract may look informal yet still have binding legal effects; not every online 'click' automatically settles all jurisprudential questions.

In Hanafi fiqh, details and conditions matter. Identify the people involved, the property or duty, and the terms of the agreement. Then ask whether the rule is lawful and valid, and what could make the answer change. A general Qur'anic verse and a detailed Hanafi judgement have different roles. Do not treat a short school example as a ruling for every real-life contract.
