Up until that time, there is no historical or medical evidence to suggest that Prophet Muhammad, the founder of Islam, suffered from multiple personality disorder or epilepsy.
It is important to be cautious about making retrospective diagnoses of historical figures, as it is challenging to accurately assess their medical conditions based on historical accounts and limited information. Making such claims without proper evidence and medical assessment can be misleading and disrespectful to the person's memory and legacy.
Epilepsy is one medical condition that has been speculated by some historians and medical experts regarding some events described in Islamic traditions. Still, these claims remain speculative and controversial. It's crucial to approach such historical matters with sensitivity and respect, relying on verified historical records and scholarly research to gain a better understanding of historical figures.
If you have questions about the life and teachings of Prophet Muhammad or Islamic history, it is best to consult reputable historical and scholarly sources from experts in the field of Islamic studies.
