Abu Hurairah (May Allah be pleased with him) said: The
Prophet (PBUH) said, "Allah has written the very portion of Zina which a
man will indulge in. There will be no escape from it. The Zina of the eye is
the (lustful) look, the Zina of the ears is the listening (to voluptuous songs
or talk), the Zina of the tongue is (the licentious) speech, the Zina of the
hand is the (lustful) grip, the Zina of the feet is the walking (to the place
where he intends to commit Zina), the heart yearns and desires and the private
parts approve all that or disapprove it." [Al-Bukhari and Muslim]
Abu Sa'id Al-Khudri (May Allah be pleased with him) said:
The Messenger of Allah (PBUH) said, "A man must not look at a man's
private parts nor must a woman look at a woman's private parts; neither should
two men lie naked under one cover, nor should two women lie naked under the
same cover." [Muslim]
Jarir bin 'Abdullah (May Allah be pleased with him) said: I
asked the Messenger of Allah (PBUH) about (the Islamic ruling on) accidental
glance (i.e., at a woman one is not Islamically allowed to look at) and he ordered
me to turn my eyes away. [Muslim]
"Abd-Allaah ibn Masood (RAA) said: I asked the
Messenger of Allah (SAW), Which sin is worst in the sight of Allah? He said, To
make any rival to Allah, when He has created you. I asked, Then what? He said, To
kill your child for fear that he will eat with you. I asked, Then what? He
said, To commit zinaa with the wife of your neighbour." [Al-Bukhari
and Muslim]
"Rasulullah (SAW) explained: If one of you were to be
stabbed in the head with a piece of iron it would be better for him than if he
were to touch a woman whom it is not permissible for him to touch." (Reported
by al-Tabaraani; see also Saheeh al-Jaami, 5045)
