Al-Adab Al-Mufrad, Hadith 1092 ⓘ
'Umar ibn al-Khattab said, "Anyone who fills his eye with the contents of a house before he has been given permission has gone astray."
حَدَّثَنَا عَبْدُ اللهِ بْنُ يَزِيدَ، قَالَ: حَدَّثَنَا شُعْبَةُ، عَنْ عَطَاءِ بْنِ دِينَارٍ، عَنْ عَمَّارِ بْنِ سَعْدٍ التُّجِيبِيِّ قَالَ: قَالَ عُمَرُ بْنُ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ: مَنْ مَلَأَ عَيْنَيْهِ مِنْ قَاعَةِ بَيْتٍ، قَبْلَ أَنْ يُؤْذَنَ لَهُ، فَقَدْ فَسَقَ.
