IBNHIBBAN 4420:
from Abū Hurayrah —
[Machine] The Messenger of Allah ﷺ said, "Allah has decreed for the son of Adam his share of adultery which will inevitably happen to him; the adultery of the eyes is looking, the adultery of the tongue is speaking, and the soul desires and covets it, while the private parts either confirm or deny it."
ابن حبّان ٤٤٢٠:
عن ابو هريره —
قَالَ رَسُولُ اللَّهِ ﷺ «كَتَبَ اللَّهُ عَلَى ابْنِ آدَمَ حَظَّهُ مِنَ الزِّنَى أَدْرَكَ ذَلِكَ لَا مَحَالَةَ فَزِنَى الْعَيْنُ النَّظَرُ وَزِنَى اللِّسَانِ النُّطْقُ وَالنَّفْسُ تَتَمَنَّى ذَلِكَ وَتَشْتَهِي وَيُصَدِّقُ ذَلِكَ الْفَرْجُ أَوْ يُكَذِّبُهُ»
