Based on our narrations

when Wali al-‘Asr1 [Imam Zaman (mgehr)] emerges,  both the dead who spend their burial night and the ones who are in intermediate state feel lots of joy.

In other words, even the deceased believers are affected by this physical world.

This is the same issue that we connote, when we say “ اللهم ادخل علی اهل القبور السرور” after reading the prayers in the holy month of Ramathan.
۱-     Wali al-‘Asr is a title of Imam Zaman [Imam Mahdi (mgehr)] which means he is the Imam of Era and has control on the time.
