Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Aamir bin Mus'ab that Hazrat Aisha (may Allah be pleased with her) performed i'tikaf in place of her brother after his death.

12972 - Jarir narrated from Layth who said: Tawus was asked about a woman who died while she was required to perform i'tikaf for a year in the Sacred Mosque, and she had (four) (1) (sons) (2), all of whom wished to fulfill it on her behalf. Tawus said: All four of you should perform i'tikaf in the Sacred Mosque for three months and fast.

It is narrated from Ubaidullah bin Abdullah bin Utbah that a woman had vowed to observe i'tikaf for ten days, but she passed away and could not perform the i'tikaf. Ibn Abbas (may Allah be pleased with them) said: Observe i'tikaf on behalf of your mother.

Ibrahim says that the missed I'tikaf should not be made up on behalf of the deceased.

Hazrat Tawus, regarding a vow made for a deceased person, says that a decision will be made among his heirs, and if someone has fasts of a year due upon him, then if the heirs wish, they may observe the fasts; each of the heirs will observe three months of fasting.
