What it is recommended to say when having intercourse
Sahih Muslim
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، - وَاللَّفْظُ لِيَحْيَى - قَالاَ أَخْبَرَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ سَالِمٍ، عَنْ كُرَيْبٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لَوْ أَنَّ أَحَدَهُمْ إِذَا أَرَادَ أَنْ يَأْتِيَ أَهْلَهُ قَالَ بِاسْمِ اللَّهِ اللَّهُمَّ جَنِّبْنَا الشَّيْطَانَ وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنَا فَإِنَّهُ إِنْ يُقَدَّرْ بَيْنَهُمَا وَلَدٌ فِي ذَلِكَ لَمْ يَضُرَّهُ شَيْطَانٌ أَبَدًا ".
Ibn" Abbas (Allah be pleased with thern) reported that Allah's Messenger (ﷺ) said: If anyone amongst you intends to go to his wife he should say: In the name of Allah,0 Allah protect us against Satan and keep away the Satan from the one that you have bestowed upon us, and if He has ordained a male child for them, Satan will never be able to do any harm to him.
