It is narrated from the narrator of the previous Hadith from Mu‘awiyah ibn ‘Ammar who has narrated the following: “About the case of a woman who makes a will to set free a slave, pay charity and al-Hajj but there is not enough, he (the Imam) (a.s.), said that first is al-Hajj because it is obligatory and if anything remains extra then spend something on charity and something for setting free a slave.’” حسن كالصحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (23/30))
