"Umar's Marriage to Umm Kulthum" is an academic book that addresses a significant historical event in Islamic history. The marriage between Umar ibn al-Khattab and Umm Kulthum bint Ali took place in the year 17 AH (637-638 AD) and is a topic of great interest due to differing views between Shia and Sunni regarding the identity of Umm Kulthum. The book highlights the various perspectives and arguments presented in this debate and offers a detailed analysis of the relevant hadiths. The authors, Miriam T. Timpledon, Susan F. Marseken, and Lambert M. Surhone, utilize a variety of sources to illuminate the historical contexts and differing interpretations. This work is particularly valuable for readers interested in the history of Islam and the associated theological discussions.
