In an anecdote in the Holy Bible, there is a rumor that because the Prophet David wanted to marry a woman named Bathsheba, whom he saw, he commissioned her soldier husband Uriah the Hittite to cause him to die in the most critical places of the army. In Islamic sources, some narrations originating from Israiliyyat have been conveyed in many different ways. Likewise, in some Islamic sources, this incident, which is attributed to the Prophet David, was unfortunately also linked to the marriage of the Prophet Muhammad and Zaynab b. Jahsh. In addition, there is a claim that the Prophet Muhammad sent Zayd b. Haritha, who was Zaynab b. Jahsh's ex-husband, to many wars and eventually caused his death in Mu'ta war. First, the so-called incident between Prophet David and Uriah the Hittite will be discussed, and thereafter, Prophet Muhammad and Zaynab b. Jahsh's marriage will be thoroughly addressed in the study. In addition, it will be revealed that the incident that was attributed to the Prophet David was in no way similar to the incident of assigning Zayd b. Haritha as a commander.
