Dua before having sexual relations

Some of the scholars stated that Basmalah before eating is obligatory. Basmalah before having sexual intercourse is also recommended. The Two Sahihs recorded that Ibn `Abbas said that the Messenger of Allah said,

«لَوْ أَنَّ أَحَدَكُمْ إِذَا أَرَادَ أَنْ يَأْتِيَ أَهْلَهُ قَالَ: بِسْمِ اللهِ اللَهُمَّ جَنِّبْنَا الشَّيْطَانَ وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنَا،فَإنَّهُ إِنْ يُقَدَّرْ بَيْنَهُمَا وَلَدٌ لَمْ يَضُرَّهُ الشَّيْطَانُ أَبَدًا»

(If anyone of you before having sexual relations with his wife says, 'In the Name of Allah. O Allah! Protect us from Satan and also protect what you grant us (meaning the coming offspring) from Satan,' and if it is destined that they should have a child then, Satan will never be able to harm that child.)
