BAYHAQI 13511:
from Rasūl Allāh Ṣllá —
[Machine] The Messenger of Allah ﷺ said, "For every son of Adam, there is a share of zina. The eyes commit zina through their gaze, and their zina is looking. The hands commit zina through their touch, and their zina is grasping. The feet commit zina through their walk, and their zina is walking. The mouth commits zina, and its zina is kissing. The heart desires and wishes, and it either confirms or denies it." Abu Hurairah heard and witnessed this.

عن رسول الاه صلى —
قَالَ رَسُولُ اللهِ ﷺ لِكُلِّ ابْنِ آدَمَ حَظُّهُ مِنَ الزِّنَا فَالْعَيْنَانِ تَزْنِيَانِ وَزِنَاهُمَا النَّظَرُ وَالْيَدَانِ تَزْنِيَانِ وَزِنَاهُمَا الْبَطْشُ وَالرِّجْلَانِ تَزْنِيَانِ وَزِنَاهُمَا الْمَشْيُ وَالْفَمُ يَزْنِي وَزِنَاهُ الْقُبَلُ وَالْقَلْبُ يَهُمُّ أَوْ يَتَمَنَّى وَيُصَدِّقُ ذَلِكَ الْفَرْجُ أَوْ يُكَذِّبُهُ شَهِدَ عَلَى ذَلِكَ أَبُو هُرَيْرَةَ سَمِعَهُ وَبَصُرَهُ
