Praise be to Allaah.
It seems that your mother in is need of care and compassion, and at the
same time she seems to be feeling some nostalgia for the past, by wishing to go back to
her former corrupt religion. The former stems from her losing her position through the
divorce which has taken place, so you and your brothers and sisters must make up for what
she has lost to reduce the pain and bitterness of the humiliation she has suffered through
this divorce. Most of the responsibility will fall on your shoulders because you are the
closest of her children to her, as you say. You must enjoin your brothers and sisters to
fulfil their duties of caring for her and looking after her, by speaking kindly to her,
consoling her gently, serving her, taking care of her affairs, spending on her, visiting
her, keeping in touch and upholding the ties of kinship, until things settle down for her
and she feels better.
With regard to the second issue, her nostalgia for her former, corrupt
religion, you must deal with this problem by advising her and making the effort to explain
the seriousness of apostasy and returning to kufr. Tell her about the hadeeth of the
(peace and blessings of Allaah be upon him): “There are three things, if
a person has them, he has found the sweetness of faith: if Allaah and His Messenger are
more beloved to him than anyone or anything else; if he loves another and does not love
him for any reason other than for the sake of Allaah; and if he would hate to return to
kufr after Allaah has saved him from it as much as he would hate to be thrown into the
fire.” (Reported by al-Bukhaari and Muslim. This version was narrated by
Muslim in his Saheeh, no. 460).
Alarm her with the aayah (interpretation of the
meaning): “Verily, those who have turned their backs as disbelievers after the
guidance has been manifested to them, Shaytaan has beautified for them (their false
hopes), and (Allaah) prolonged their term (age).” [Muhammad 47:25]. Explain to
her the fate of the apostate as described in the Qur’aan (interpretation of the
meaning): “…And whosoever of you turns back from his religion and dies as a
disbeliever, then his deeds will be lost in this life and in the Hereafter, and they will
be the dwellers of the Fire. They will abide therein forever.” [al-Baqarah 2:217].
If you try your hardest, you will not be to blame if something that you
dislike happens after that. But whatever the case, you must not carry out any last wishes
or will to burn the body after death (cremation), because this is something that is viewed
as abhorrent in Islamic sharee’ah (see Question #675). We ask Allaah for guidance and
steadfastness in Islam, and for a good end, for your mother and for all the Muslims. May
Allaah bless our Prophet Muhammad.
