Narrated Ibn `Abbas:
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ ، حَدَّثَنَا هَمَّامٌ ، عَنْ مَنْصُورٍ ، عَنْ سَالِمِ بْنِ أَبِي الْجَعْدِ ، عَنْ كُرَيْبٍ ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَمَا إِنَّ أَحَدَكُمْ إِذَا أَتَى أَهْلَهُ وَقَالَ بِسْمِ اللَّهِ اللَّهُمَّ جَنِّبْنَا الشَّيْطَانَ، وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنَا. فَرُزِقَا وَلَدًا، لَمْ يَضُرُّهُ الشَّيْطَانُ " .
The Prophet (ﷺ) said, "If anyone of you, when having sexual relation with his wife, say: 'In the name of Allah. O Allah! Protect us from Satan and prevent Satan from approaching our offspring you are going to give us,' and if he begets a child (as a result of that relation) Satan will not harm it."
