His contributions to horse racing were recognized internationally.

He held multiple citizenships, including British, French, Swiss, and Portuguese, and was known for his efforts to bridge the gap between Islamic and Western cultures.

His death has prompted tributes from global leaders and organizations.

The announcement of his successor is expected following the reading of his will.
