The ruling on a son praying the funeral prayer for his mother who abandons the prayer

Question:
And also how a son should treat his mother,

Answer:
if she intentionally abandons the prayer and persists in this without repenting before her death, and he knows from her condition that he will not pray over her and will not follow her funeral procession; he does not pray over her and does not attend her funeral.
As for if she abandons the prayer due to her illness, thinking that... because some patients think it is permissible for them to abandon the prayer, thinking that Allah has excused them and that Allah will judge them; some patients hold this view. This does not make her a disbeliever; she is mistaken, but she does not commit disbelief on this account, because she did not abandon the prayer intentionally, but rather because she thinks it is permissible for her to do so, believing that the Lawgiver permits this. She is a mistaken ignoramus, but she does not commit disbelief. Yes.
