4919 - وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ : "إِنَّ أَحَدَكُمْ لَيَأْتِي أَهْلَهُ فَتَخْرُجُ مِنْ تَحْتِهِ فَلَوْ أَصَابَتْ زِنْجِيّاً لَتَشَبَّثَتْ بِهِ فَإِذَا أَتَى أَحَدُكُمْ أَهْلَهُ فَلْيَكُنْ بَيْنَهُمَا مُدَاعَبَةٌ فَإِنَّهُ أَطْيَبُ لِلْأَمْرِ".
Hadith.4919 - Imam Jafar ibn Muhammad Al-Sadiq (as) said: "Indeed, one of you may approach his wife, and she departs from beneath him; if she were to encounter a black man, she would cling to him. Therefore, when one of you approaches his wife, there should be mutual foreplay between them, for it is more pleasant and better for intimacy."
