عن معاوية بن حيدة قال: قال رسول الله صلى الله عليه وسلم: ثلاثة لا ترى أعينهم النار: عين حرست في سبيل الله وعين بكت من خشية الله وعين كفت عن محارم الله (مجمع الزوائد، الرقم: 9490)

Hazrat Mu’aawiyah bin Haydah (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “There are three people whose eyes will not see the fire of Jahannum (i.e. they will be kept away from Jahannum.) The (first person is the one whose) eye was guarding (the Muslims) in the path of Allah Ta‘ala, the (second person is the one whose) eye shed tears out of the fear of Allah Ta‘ala, and (the third person is the one whose) eye was restrained from looking at haraam (i.e. all those things which Allah Ta‘ala has prohibited one from looking at).”
