Hanad bin al-Sari bin Mus'ab هناد بن السري بن مصعب · Marriage (Kitab Al-Nikah)

Ibn ‘Abbas reported the Prophet (ﷺ) as saying “If anyone who means to have intercourse with his wife says “In the name of Allaah, O Allaah, keep us away from the devil and keep the devil away from what You hast provided us.” It will be ordained that no devil will ever harm the child born to them.
