ذِكْرُ الشَّيْءِ الَّذِي إِذَا قَالَهُ الْمَرْءُ عِنْدَ الْوَطْأِ لَمْ يَضُرَّ الشَّيْطَانُ وَلَدَهُ
Ibn ‘Abbas reported the Prophet ﷺ as saying “If anyone who means to have intercourse with his wife says “In the name of Allaah, O Allaah, keep us away from the devil and keep the devil away from what You hast provided us.” It will be ordained that no devil will ever harm the child born to them. (Using translation from Abū Dāʾūd 2161)
أَنَّ النَّبِيَّ ﷺ قَالَ «أَمَا إِنَّ أَحَدَكُمْ لَوْ أَنَّهُ إِذَا أَرَادَ أَنْ يَأْتِيَ أَهْلَهُ قَالَ بِسْمِ اللَّهِ اللَّهُمَّ جَنِّبْنَا الشَّيْطَانَ وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنَا ثُمَّ رُزِقَا وَلَدًا لَمْ يَضُرَّهُ الشَّيْطَانُ»
