Is the waiting period for a woman whose husband has died prescribed for an elderly woman?

Question:
May Allah reward you with good, and may He do you good. Since she mentions that she is fifty years old and that she has no hope of marriage, does the waiting period depend on these matters, or is it a matter prescribed even for an elderly woman, if she were older than fifty?

Answer:
The waiting period following the death of a husband is obligatory for the widow in all cases, whether she is young or old, and whether she is of those who menstruate or not. The waiting period after her husband's death is obligatory upon her. His saying, the Exalted: This is general for every woman whose husband has died, whether she is old, young, or of middle age. Yes.
