Is it Islamically permissible to retract from a lease agreement that was made verbally?

An ijarah (lease/rental) is a binding contract for both parties, so neither party may unilaterally revoke it after it has been concluded, except with the other party's consent. This is because it is a binding compensatory contract, similar to a sale. If you agree to the rent and conclude the contract, it becomes binding. If the tenant's going to show the property to his family necessitates stipulating an option for him to revoke if his family is not pleased, then such a condition is valid, and the revocation would be permissible for the one who holds this option. However, if there is no option stipulated, the contract is binding on both parties, and you cannot retract from it except with the tenant's consent, for Allah the Almighty says: "And fulfill [every] commitment. Indeed, the commitment is ever [that about which one will be] questioned," and "O you who have believed, fulfill [all] contracts."
