The book related the true stories of the prophets using the descriptions found in the versed of the Quran and the authentic  narrations of prophet Muhammad SAW the people of the book and those who study religion identify with the Jewish and the Christian bibles as a source of the stories of the prophets, however the previous scriptures have been distorted , and the truth has been mixed with falsehood, so these writings are not the true descriptions of the prophets. Instead the true descriptions are found in the Quran and the preserved chains of narrations to the last prophet.
