question #1 Sahih al-Bukhari 5165, Book 67, Hadith 100 : What is the significance of reciting a specific supplication before engaging in marital relations in Islam?

The Prophet (ﷺ) said, “If anyone of you, when having sexual intercourse with his wife, says: Bismillah,
Allahumma jannibni-Sh-Shaitan wa jannib-ish-Shaitan ma razaqtana, and if it is destined that they
should have a child, then Satan will never be able to harm him.”
