The document discusses the importance of contracts in both Islamic law and common law. In Islam, a contract (aqd) requires offer and acceptance, as well as the consent of both parties. The terms must be for a halal object and allowed under Islamic revelation. Written contracts are emphasized in the Quran and by the Prophet Muhammad. Fulfilling obligations and avoiding deception are stressed. In common law, contracts create legally binding relationships if they meet requirements like offer, acceptance, and consideration. Written contracts are preferred as they clearly outline parties' expectations and responsibilities.
