I have not—and will not—deny reincarnation itself; my comment is specifically on the utility of researching this field. Ibn Shu’bah (may his secret be sanctified) was a scholar among scholars, but was he infallible?

I hope you will post the text you referred to so that everyone can see it and benefit from it as scientific and scholarly material, as the book may not be available to some brothers and sisters. Furthermore, I would appreciate it if you could dedicate a specific chapter or a separate answer to the following question: Does a man become a woman and a woman become a man? And does what we see today—young men who dress like women, wear their ornaments, and exhibit feminine behaviors—have any connection to this subject of reincarnation? Similarly, what about women who resemble men? I repeat, I am not denying reincarnation.

"However, I negate every science that revolves around it because it is not within the capacity of the created to behold the knowledge of the Creator. Furthermore, another question: even if we attained this knowledge, delved into it, and dove into the depths of its sea, what is the desired benefit that I could extract? I have searched into this matter myself and reached a certain conclusion—perhaps it holds a piece of the Great Truth, or perhaps nothing of it at all, for God knows best."
