What is the ruling on breaking a Fatiha that was recited for the fulfillment of a personal need, and does it take the ruling of an expiation for an oath, and does one Fatiha equal 44 oaths?

Sharia (definition) contracts are divided into binding contracts, such as lease and sale, which cannot be annulled after completion except with the agreement of both parties, and permissible contracts, such as agency and ju'alah (reward-based contracts), which either party may annul. If the contract is a lease, it cannot be annulled except with the agreement of the other party. If it is a ju'alah or agency contract, its annulment is permissible even if the other party does not agree, but if you annul the contract after the work has commenced, then he is entitled to a fair wage (ujrat al-mithl) from you. Making the recitation of Al-Fatihah a sign of offer and acceptance is not from the guidance of the Salaf (pious predecessors), and it is better to abandon it. We know of no basis for Al-Fatihah being equivalent to 44 oaths, nor is there any expiation for someone who annuls the contract.
