All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
Saying that we have seven lives is a wrong statement which contradicts religion as well as reality. It is confirmed in religion that we have two lives, a worldly life, which is the life before death, and the Hereafter, which is the life after death.
As regards the senses and reality, then there is no sign for these seven lives in reality.
With regard to hypnosis, whether that is by using the Jinn or by insinuation, then there no transfer of the soul of a person to the body of another person, but the jinn help inspiring the inner self of a person or by using insinuation for this purpose.
Allaah Knows best.
