On March 10, 1953, the Viceroy of Yemen, Saif el Islam el Hassan, arrived in Wiesbaden for a spa stay of several weeks. On March 16, the magistrate decided that Mayor Kluge should ask him to make an entry in the Golden Book during a private meeting.

At the end of his cure, the monarch praised Wiesbaden's water, nature and doctors, who had improved his health. On 6 Shaaban 1372 according to the Islamic calendar, Saif el Islam el Hassan signed the Golden Book in Arabic script from right to left.

After a tour of the festively decorated town hall, the delegation returned to the sanatorium in the Nero Valley before returning to Yemen a few days later.
