Hassan II Mosque in building and beautifying the mosque. However, the building was not completed on schedule which delayed inauguration. The formal inauguration was subsequently chosen to be the 11th Rabi' al-awwal of the year 1414 of the Hegira, corresponding to 30 August 1993, which also marked the eve of the anniversary of Prophet Muhammad’s birth. It was dedicated to the Sovereign of Morocco. Construction costs, estimated to be about 585 million euro, were an issue of debate in Morocco, a lower mid-income country. While Hassan wished to build a mosque which would be second in size only to the mosque at Mecca,
Mohamed Medbouh was achieved without difficulty. He became governor of Casablanca and then Minister of Posts. King Hassan II succeeded to the throne on 26 February 1961. Medbouh was made the king's chief aide-de-camp. In July 1963 an alleged plot by the leftist National Union of Popular Forces party to kill the king in his bed was foiled. The plotters were said to have obtained detailed plans of the palace from Major Mohamed Medbouh, although Medbouh was not implicated. He was made head of the Royal Military Cabinet in 1967. He often went riding with Hassan II, or played golf with him.
