Dua before marital relations

The Prophet ﷺ said: "If one of them, when he comes to his wife, were to say:

bismillāh, allāhumma jannibnī al-shayṭān, wa-jannib al-shayṭān mā razaqtanā

(In the name of Allah. O Allah, keep Satan away from me, and keep Satan away from what You grant us; then if a child is decreed between them in that, or a child is ordained, Satan would never harm him.)

قَالَ النَّبِيُّ ﷺ: «أَمَا لَوْ أَنَّ أَحَدَهُمْ يَقُولُ حِينَ يَأْتِي أَهْلَهُ:

بِاسْمِ اللَّهِ، اللَّهُمَّ جَنِّبْنِي الشَّيْطَانَ، وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنَا،

ثُمَّ قُدِّرَ بَيْنَهُمَا فِي ذَلِكَ أَوْ قُضِيَ وَلَدٌ، لَمْ يَضُرَّهُ شَيْطَانٌ أَبَدًا».
