The problem and the solution. As the second largest religion on earth, Islam has been in existence for more than 14 centuries. Today, Islam continues to grow in many parts of the world, including Europe and North America where Muslims comprise a notable minority. As our societies become more diverse, it is not uncommon in many major cities to have a Muslim colleague at work, classmate in school, or neighbor in the community. These areas are within the practice and research realm of human resource development (HRD). Therefore, understanding and appreciating the Islamic worldview of adult learning and the daily practices of its followers will contribute to resolving philosophical and cultural clashes in the work of HRD professionals as trainers, researchers, educators, and consultants throughout the world.
