Chapter: Disliking the visitor to look at private parts of the house
Hadith Number: 412
412/531 عن عبد الله بن ابي الهذيل قال: دخل عبد الله بن مسعود على مريض يعوده- ومعه قوم، وفي البيت امراة – فجعل رجل من القوم ينظر إلى المراة، فقال له عبد الله:" لو انفقات عينك، كان خيرا لك".
It is narrated from Abdullah bin Abi Huzail that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) went to visit a sick person. Some other people were with him, and there was also a woman in the house. One of the people began to look towards the woman, so Sayyiduna Abdullah (may Allah be pleased with him) said: If your eye were to be blinded, it would be better for you.
