Acceptance of the repentance of one afflicted with an illness from which recovery is not expected

Is the repentance of one afflicted with an illness from which recovery is not expected valid?
Yes.
The repentance of a person who has despaired of his life is valid, whether due to an illness from which recovery is not expected, such as cancer for example, or because he has been brought for execution, such as a man brought to be avenged, even if the executioner’s sword is at his neck, or in the case of a married man who committed unlawful sexual intercourse and became liable to stoning, even if the stones have already been gathered to stone him. His repentance is valid; for Allah the Exalted accepts the repentance of a person as long as he has not reached the point of death,Allah the Exalted said: [Al-Nisa: 17] And the meaning of His saying: [Al-Nisa: 17] is: they repent before death,By the saying of Allah the Exalted after this verse: [Al-Nisa: 18] But repentance must have five conditions: sincerity, regret for what was done, ceasing from it immediately, resolving not to return to it in the future, and that the repentance be made at a time when it is accepted,Meaning: namely before death or before the sun rises from the west.
