Tehran police have discovered a handwritten letter by the late Mohammad Reza Shah Pahlavi (1919-1980) during a raid on an illegal antique shop, the Iranian Students News Agency (ISNA) reported.

The police reportedly found the letter inside a rare, stolen Quran. The letter bears the Pahlavi royal stamp on the top and Shah’s signature at the bottom. In the letter, the Shah highlights the importance of placing the correct diacritical marks (or accents) in the text before the publication of the Quran.
