In the Name of Allāh, the Ever Merciful, the Bestower of Mercy
The shaykh (رحمه الله) said:
The Ḥadīth which reported the merit of dying on a Friday is inauthentic, since an individual is rewarded based on his voluntary actions [i.e. actions he did out of his free will]. The death of an individual on a Friday is not by choice [i.e. is not of his free will]. If death came to him on a Thursday, he is incapable of delaying it until Friday. [Similarly,] he is incapable of expediting it to Friday, if it was written for him to die on a Saturday.
[Thus,] every Ḥadīth that mentioned the merit of dying on a particular day is inauthentic because recompense is based on the voluntary actions of the slave.
