Is there a reward for a woman who makes du'a' (supplication) for her husband after his death?

Question:
Shaykh, may Allah preserve you. In one of her questions, she asks about the deceased: that among the ongoing good deeds is a righteous son who makes du'a' for him. If he does not have a righteous son, but has a righteous wife, does this wife equal the righteous son? And this woman teaches her young children, who have not yet reached puberty, to make du'a' for their father. Does she receive a reward for that?

Answer:
Yes, this is a good thing. Making du'a' for the Muslim, and especially for a woman to make du'a' for her husband, and for a husband to make du'a' for his wife, and for a relative to make du'a' for his relatives or for his Muslim brothers. This is prescribed (mashru'), , , "My Lord, forgive me and my parents." All of this is required and prescribed: that a person makes du'a' for himself, makes du'a' for his relatives, and makes du'a' for his Muslim brothers. Yes.
