In "A Call to Coexistence," Dr. Amr Khaled discusses the biographies of the four Imams, focusing on their efforts to eliminate division and promote harmony among people. He chose these Imams because they lived in an era of significant openness, renewal, science, and an extraordinary cultural movement. This period also saw a cultural invasion from other cultures like the Persians and Romans. Despite these challenges, the Imams managed to coexist with different cultures without losing their identity, preserving the religion and culture of the nation while avoiding isolation. The Imams are: Imam Abu Hanifa, Imam Malik, Imam Al-Shafi'i, and Imam Ahmad ibn Hanbal. Publishing house: Arab Scientific Publishers / Lebanon. Number of Pages: 256. Year of publication: 2009.
