This is only a (3) days amal, experienced again and again. To show such a secret thing is heart touching. after saying prayer of isha, stand near the feet of a coffin with buried dead one, and recite the verse (12000) times, see the dead person in imagination, as he is in front of you. on 3rd day amil will see the coffin will open and he will find the dead one in front of him, now amil can ask each and every thing, he will reply you. Amil can ask any secret but remember you can not ask him what goes on towards him after death. Asking such a question is very risky and dangerous. if buried man is a valli Ullah only a pious man should do this amal Insha Allah amil will talk to him on first night if burried man is miracoulous man.
The first verse of Sura Muzammil and then First word of second verse, That is written here:
YA AYO HAL MUZAMILLO QUM
أَيُّهَا الْمُزَّمِّلُ. قُم
