that the Prophet said: “When anyone of you has intercourse with his wife, let him say: Allahumma jannibnish-Shaitana wa jannibish-Shaitana ma razaqtani (O Allah, keep Satan away from me and keep Satan away from that with which You bless me).' Then if they have a child, Allah will never allow Satan to gain control over him or he will never harm him.” (Using translation from Ibn Mājah 1919)
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لَوْ أَنَّ أَحَدَكُمْ أَوْ لَوْ أَنَّ أَحَدَهُمْ إِذَا أَتَى امْرَأَتَهُ قَالَ اللهُمَّ جَنِّبْنِي الشَّيْطَانَ وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنِي ثُمَّ كَانَ بَيْنَهُمَا وَلَدٌ إِلا لَمْ يُسَلَّطْ عَلَيْهِ الشَّيْطَانُ أَوْلَمْ يَضُرَّهُ الشَّيْطَانُ
