Dua: When Going To Sleep With The Spouse
Narrated Ibn`Abbas: Allah’s Apostle said, If anyone of you, when intending to have a sexual relation(Sleep) with his wife(Spouse), 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).
بِاسْمِ اللَّهِ اللَّهُمَّ جَنِّبْنَا الشَّيْطَانَ وَجَنِّبْ الشَّيْطَانَ مَا رَزَقْتَنَا
Sahih Bukhari 7396
