Muhammad's marriage to Zaynab bint Jash was ordained by Allah to set an example for believers regarding the permissibility of marrying the divorcees of adopted sons.

The Quranic narrative suggests that Allah caused Muhammad to desire Zaynab, leading to her divorce from Zaid. This raises ethical questions about divine influence over personal relationships, particularly when it involves a married woman. In contrast, the Bible teaches that desiring another's spouse is akin to committing adultery in one's heart, as stated in Matthew 5:27-28. Furthermore, the Bible condemns divorce, highlighting God's disdain for treachery against one's spouse, as seen in Malachi 2:13-16. Therefore, from a Biblical standpoint, Muhammad's actions could be interpreted as morally objectionable, as they violate the principles of fidelity and respect for marriage. Additionally, shortly after this event, the Quran abolishes the practice of adoption, which further complicates the rationale behind this marriage, suggesting a lack of consistency in moral teachings.
