He (the Imam) said, ‘Have you not heard the words of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, “If you find something better than that for which you have taken an oath, then you can disregard it.’”” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (4/321))
