Sayyidina Abu Dharr (RA) reported that Allah’s Messenger (SAW) said, “If anyone slid the curtain (of a house) and his sight penetrated in the house before he sought permission for himself and he saw the secret of its .folks, then he touched the limit that was not lawful to him to touch. If meanwhile someone had pierced his eyes while they were penetrating (the house) then I would not get him retribution. But, if a man goes to a house that has no curtains neither is it shut and his eyes fall inside then he is not in error that fault lies with the people of the house.”
