Is it true that the deceased father asked the mother for a blanket in a dream to cover himself with?

This vision does not necessitate anything, but it is prescribed to give charity on behalf of the father, whatever is affordable, and its reward will reach him; for the saying of the Prophet, peace and blessings be upon him: "Will she have a reward if I give charity on her behalf?" He said: "Yes, so give charity on behalf of your mother." The scholars have unanimously agreed that charity and supplication benefit the deceased.
