A romantic letter discovered by an archaeologist in 1892 in the then newly developing city of Ismailia in north-east Egypt has opened up new questions on the sexual life of Muhammad. Muslims regard Muhammad for over a thousand years as a holy prophet, someone who has heard from Allah (God), but the content of the fragile letter which was discovered takes some philosophers and historians into a new understanding of the central figure behind the Quran and Islam. Was the prophet Muhammad only a heterosexual? Or was he hiding a surreptitious love affair with another man that has now only emerged with the finding of this romantic letter? This book looks into the validity of the unearthed letter and what it tells about a side of Muhammad which has never before been explored.
