He (the Imam) said, ‘Expiation is obligatory when one takes an oath not to sell an asset or buy but then he changes his mind. If one takes an oath about something which is better for him to do than not to do and he does what is good then there is no expiation on him, it is only of the temptations of Satan.”’ شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (4/326))
