question #3 Sahih al-Bukhari 7396, Book 97, Hadith 25 : What role does intention and prayer play in safeguarding one’s family from spiritual harm in Islam?

Allah’s Messenger (ﷺ) said, “If anyone of you, when intending to have a sexual relation (sleep) with his wife,
says: Bismillah, Allahumma jannibna ashShaitan, wa Jannib ash-Shaitana ma razaqtana, Satan would
never harm that child, should it be ordained that they will have one. (Because of that sleep).
