Narrated Ibn ‘Abbas:
I did not see anything so resembling minor sins as what Abu Huraira said from the Prophet, who
said, “Allah has written for the son of Adam his inevitable share of adultery whether he is aware of it
or not: The adultery of the eye is the looking (at something which is sinful to look at), and the adul –
tery of the tongue is to utter (what it is unlawful to utter), and the innerself wishes and longs for
(adultery) and the private parts turn that into reality or refrain from submitting to the temptation.”
