Is it permissible to use a device that predicts biological age and time of death, and identifies potential genetic diseases?

Allah Almighty has exclusively reserved the knowledge of future unseen matters. Therefore, anyone who claims to know it is a liar, an fabricator, and an infidel. The proof is His (Allah's) saying: "And with Him are the keys of the unseen; none knows them except Him." The Prophet, peace and blessings be upon him, mentioned the five keys of the unseen that none knows except Allah: knowledge of the Hour, the descent of rain, what is in the wombs, what a soul will earn tomorrow, and where a soul will die. Thus, anyone who claims to know the time of a person's death, even by inferring from signs, is a fabricator and a liar. Accordingly, it is forbidden to buy, sell, or use a device that claims to know the time of a person's death. However, using it for other medical purposes is permissible.
