The Ruling on Disclosing the Secrets of the Living and the Dead

Question:
If the person who held the secret passes away?

Answer:
It varies. If the harm is removed by his death, there is no harm; but if the harm does not go away, the secret must not be disclosed. For example, the story of Fatimah when the Prophet (peace and blessings be upon him) confided in her and told her that his time was near. She wept. Then the Prophet (peace and blessings be upon him) confided in her again and mentioned that she would be the lady of the women of Paradise, so she laughed. Aisha asked her about it, but she did not tell her. When the Prophet (peace and blessings be upon him) passed away, Aisha asked her again, and she said: Yes, I will tell you now, but before that, it was a secret. Because with the death of the Prophet (peace and blessings be upon him), the concern regarding the disclosure that his time was near was removed, as the death had already occurred.
Q: If it was stipulated that the secret not be disclosed, even if the holder dies?
A: It must not be disclosed.
Q: Secrets in general?
A: Secrets whose disclosure causes harm, and it is feared that the owner will not be pleased, whether they concern marital relations or other matters.
Q: Is a woman not allowed to tell her mother or her sister?
A: She must not disclose the secret, not to her mother, not to her sister, and not even to her father.
Q: If this woman is divorced from a man, and he wants to marry another woman, and she fears that he might harm her sister?
A: A secret is not disclosed unless its owner permits it or the cause for keeping it is removed.
