Malcolm organizes a journey to the sacred city of Mecca. During his trip, he makes stopovers in Frankfurt, Germany, and Cairo, Egypt, where he enjoys sightseeing and meets warm, welcoming individuals. When he reaches Jedda, an old port city in Saudi Arabia, he experiences a brief delay at the airport. Malcolm discovers he must first be examined by a Muslim high court that scrutinizes potential non-genuine converts to Islam before they can enter Mecca.

Confused and unable to converse with the Arabic speakers he encounters, Malcolm reaches out to Dr. Assam for help. Dr. Assam and his family offer Malcolm food and a place to stay. The high court gives the green light for Malcolm's pilgrimage.

During his spiritual journey, Malcolm comes across thousands of individuals from diverse racial and ethnic backgrounds. He is struck by the profound sense of unity and kinship practiced by everyone, regardless of their appearance. As a result, Malcolm pens letters to his loved ones and friends in the United States, sharing his newfound sense of togetherness and brotherly love.
