Sahih Muslim, 1403c
sahih

Jabir heard Allah's Messenger (ﷺ) say:

When a woman fascinates any one of you and she captivates his heart, he should go to his wife and have an intercourse with her, for it would repel what he feels.

وَحَدَّثَنِي سَلَمَةُ بْنُ شَبِيبٍ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ، حَدَّثَنَا مَعْقِلٌ، عَنْ أَبِي الزُّبَيْرِ، قَالَ قَالَ جَابِرٌ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏

‏ إِذَا أَحَدُكُمْ أَعْجَبَتْهُ الْمَرْأَةُ فَوَقَعَتْ فِي قَلْبِهِ فَلْيَعْمِدْ إِلَى امْرَأَتِهِ فَلْيُوَاقِعْهَا فَإِنَّ ذَلِكَ يَرُدُّ مَا فِي نَفْسِهِ ‏
