(13) باب السُّؤَالِ بِأَسْمَاءِ اللَّهِ تَعَالَى، وَالاِسْتِعَاذَةِ بِهَا
Narrated Ibn `Abbas:
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). (ES)
