Al-Jammāl sheds light upon the issue of Abū Bakr Al-Rāzī's apostasy. Al-Rāzī was a famous Muslim doctor who lived from 864 – 925. The debate is between two famous researchers, Dr. Yūsuf Zidayn, who is a proponent of Al-Rāzī’s apostasy and Dr. Khālid Harbī, who argues the contrary. The author declares that the court will put an end to this problem next August.
