Q 2: A week after my father's death, my mother passed away. She was old and ill. Her death shocked me as the two misfortunes followed each other. I wept a lot as I could not stand this shock. According to doctors, my mother suffered from brain hemorrhage. She missed some Prayers as she was unconscious. When she felt that she was close to death,
she willed a charity to be given to the poor on her behalf as a way of making up for the missed Prayers.
It should be noted that she used to observe Prayer, fast during Ramadan even though she was weak and old. She even used to offer supererogatory Sawm.The problem here is that we do not know how much we should give in charity for missed Prayers or what the Kaffarah (expiation) for missing some prayers should be.
You have to show patience and submit to Allah's Will and Decree, seek Allah's reward through patience for the loss of your mother, and do not bewail or lament her. It is reported that bewailing, lamenting or crying out for the dead is prohibited. There is no blame on your mother in what you have mentioned
of her missing some Prayers while she was unconscious. As she was not legally competent to pray when she was unconscious. She also does not have to make Kaffarah (expiation) or give to charity to make up for the missed days; because she was unconscious when she stopped praying. (Part No. 5; Page No. 26) If you give to charity on her behalf, that would be good. May Allah (Exalted be He) reward you munificently for this. Your duty towards her is to invoke Allah for her, ask Allah to pardon her and be merciful to her, maintain her ties of blood and friendship, and do good to her friends. All this is considered as doing good deeds for your mother after her death.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
