In this gripping narrative history, Lesley Hazleton tells the tragic story at the heart of the ongoing rivalry between the Sunni and Shia branches of Islam, a rift that dominates the news now more than ever. Even as Muhammad lay dying, the battle over who would take control of the new Islamic nation had begun, beginning a succession crisis marked by power grabs, assassination, political intrigue, and passionate faith. Soon Islam was embroiled in civil war, pitting its founder's controversial wife Aisha against his son-in-law Ali, and shattering Muhammad’s ideal of unity. Combining meticulous research with compelling storytelling, After the Prophet explores the volatile intersection of religion and politics, psychology and culture, and history and current events. It is an indispensable guide to the depth and power of the Shia–Sunni split.

This book, which is written by a well known scholar, a graduate of the Sorbonne, who switched from one Muslim school of thought to another, attempts to prove that the Muslims who truly follow the authentic Sunnah of the Prophet of Islam are actually none other than those referred to as the Shi`as. It details how these Shi`as (or Shi`ites) learn this Sunnah from the closest people to the Prophet of Islam: his immediate family members. It traces the history of the Muslims of the first Islamic century and how they split into two camps, thus setting the foundations for both of these major sects. It also deals with the persecution to which the immediate family members of the Prophet of Islam were subjected and the politicians who played a major role in widening the gap between the followers of this sect and those of that. As for its style, the author restricts himself to quoting major authentic Sunni works to prove his point, relying on an in-depth study of the Islamic history in general and of that of the first century in particular. Many controversial themes are discussed in this book, including that of the infallibility of the Prophet of Islam and of the Twelve Imams who descended from Ali and Fatima, cousin and daughter of the Prophet respectively. Finally, the book concludes with an Appendix containing an Arabic poem in one thousand lines in praise of Commander of the Faithful Ali composed by an Iraqi poet for the Arabic speaking readers.

In a comprehensive study of early Islamic history, Wilferd Madelung examines the conflict which developed after Muhammad's death for the leadership of the Muslim community. He pursues the history of this conflict through the reign of the four 'Rightly Guided' caliphs to its climax in the first inter-Muslim war. The outcome of the war, which marked the demise of the reign of the Early Companions, resulted in the lasting schism between Sunnite and Shi'ite Islam. Contrary to recent scholarly trends, the author brings out Ali's early claim to legitimate succession, which gained support from the Shi'a, and offers a convincing reinterpretation of early Islamic history. This book will make a major contribution to the debate over succession. Wilferd Madelung's book The Succession to Muhammad has been awarded the Best Book of the Year prize by the Islamic Republic of Iran for the year 1997.

Imam Baqir (as) said "Since the death of the Holy Prophet (s) we Ahl ul bayt have been humiliated, made distant and have been deprived and killed and made to leave our home town and we felt frightened for our blood and the blood of our followers. The cheaters, through their lies, got nearer to the leaders, judges and governors in every city and our enemies told false and invalid traditions relating to their past leaders and quoted narrations that we had never told. They only wanted to humiliate us and wanted to accuse us of falsehood, and wanted to get nearer to their leaders through lies. After the passing away of Hassan (a.s) this became very common during the time of Muawiyah. At that time, in every city, Shias were killed, their hands and feet were cut off and they were hanged on accusations of their being near to us and talking about their love for us."
