question #1 Sahih al-Bukhari 141, Book 4, Hadith 7 : What is the significance of invoking Allah’s name before engaging in marital relations?

The Prophet (ﷺ) said, “If anyone of you on having sexual relations with his wife said (and he must say it
before starting) ‘In the name of Allah. O Allah! Protect us from Satan and also protect what you
bestow upon us (i.e. the coming offspring) from Satan, and if it is destined that they should have a
child then, Satan will never be able to harm that offspring.”
