Mishkat al-Masabih 86
عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ اللَّهَ كَتَبَ عَلَى ابْنِ آدَمَ حَظَّهُ مِنَ الزِّنَا أَدْرَكَ ذَلِكَ لَا مَحَالَةَ فَزِنَا الْعَيْنِ النَّظَرُ وَزِنَا اللِّسَانِ الْمَنْطِقُ وَالنَّفْسُ تَمَنَّى وَتَشْتَهِي وَالْفَرْجُ يصدق ذَلِك كُله ويكذبه» وَفِي رِوَايَةٍ لِمُسْلِمٍ قَالَ: «كُتِبَ عَلَى ابْنِ آدَمَ نَصِيبُهُ مِنَ الزِّنَا مُدْرِكٌ ذَلِكَ لَا محَالة فالعينان زِنَاهُمَا النَّظَرُ وَالْأُذُنَانِ زِنَاهُمَا الِاسْتِمَاعُ وَاللِّسَانُ زِنَاهُ الْكَلَامُ وَالْيَدُ زِنَاهَا الْبَطْشُ وَالرِّجْلُ زِنَاهَا الْخُطَا وَالْقَلْبُ يَهْوَى وَيَتَمَنَّى وَيُصَدِّقُ ذَلِكَ الْفَرْجُ وَيُكَذِّبُهُ»
Abu Hurayra reported that the Prophet said, “God has written for the son of Adam his share of fornication, which will inevitably reach him. The eye’s fornication is looking, the tongue’s fornication is speech, and the soul wishes and desires; the private parts confirm all of that or deny it.”
In a version from Muslim: “The son of Adam’s share of fornication, which will inevitably reach him, has been written. The fornication of the eyes is looking, of the ears is listening, of the tongue is speaking, of the hand is striking, and of the foot is walking. The heart desires and wishes, and the private parts confirm that or deny it.”
