Hadith 8:65
Narrated Ibn 'Abbas (RA):
Allah's Messenger (ﷺ) said: "If anyone who intends to have intercourse with his wife says, 'In the Name of Allah. O Allah, keep us away from the devil and keep the devil away from what You have provided us (of children)', should it be ordained that a child be born to them thereby, Satan will never harm it." [Agreed upon].
وَعَنِ ابْنِ عَبَّاسٍ - رَضِيَ اَللَّهُ عَنْهُمَا- قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ لَوْ أَنَّ أَحَدَكُمْ إِذَا أَرَادَ أَنْ يَأْتِيَ أَهْلَهُ قَالَ : بِسْمِ اَللَّهِ . اَللَّهُمَّ جَنِّبْنَا اَلشَّيْطَانَ وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنَا ; فَإِنَّهُ إِنْ يُقَدَّرْ بَيْنَهُمَا وَلَدٌ فِي ذَلِكَ , لَمْ يَضُرَّهُ اَلشَّيْطَانُ أَبَدًا". } مُتَّفَقٌ عَلَيْهِ
