Praise be to Allaah.
He must hasten to repent, even if it is at the time of
death, because the door of repentance is always open so long as he is
of sound mind. He must hasten to repent and beware of sin, even if they
have told him that the time he has left to live is short, because life
spans are in the hand of Allaah. The doctors may be mistaken in their
thinking, and he may live for a long time. Whatever the case, he must
hasten to repent and be sincere in doing so, so that Allaah will accept
his repentance. Allaah says (interpretation of the meaning):
“And all of
you beg Allaah to forgive you all, O believers, that you may be successful”
[al-Noor 24:31]
“And verily, I am indeed forgiving
to him who repents, believes (in My Oneness, and associates none in
worship with Me) and does righteous good deeds, and then remains constant
in doing them (till his death)” [Ta-Ha
20:82]
And the Prophet
(peace and blessings of Allaah
be upon him) said:
“Allaah will accept a person's
repentance so long as the death rattle has not reached his throat” i.e.,
up until the time when the dying person loses consciousness. And Allaah
is the One Whose help we seek.
