Sunan an-Nasa'i, Volume 6, Book 48, Hadith 5367 (DarusSalam) ⓘ
It was narrated that Abu Hurairah said: "Jibril, peace be upon him, asked permission to enter upon the Prophet [SAW] and he said: 'Come in.' He said: 'How can I come in when there is a curtain in your house on which there are images? You should either cut off their heads or make it into a rug to be stepped on, for we Angels do not enter a house in which there are images.'"
أَخْبَرَنَا هَنَّادُ بْنُ السَّرِيِّ، عَنْ أَبِي بَكْرٍ، عَنْ أَبِي إِسْحَاقَ، عَنْ مُجَاهِدٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ اسْتَأْذَنَ جِبْرِيلُ عَلَيْهِ السَّلاَمُ عَلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ " ادْخُلْ " . فَقَالَ كَيْفَ أَدْخُلُ وَفِي بَيْتِكَ سِتْرٌ فِيهِ تَصَاوِيرُ فَإِمَّا أَنْ تُقْطَعَ رُءُوسُهَا أَوْ تُجْعَلَ بِسَاطًا يُوطَأُ فَإِنَّا مَعْشَرَ الْمَلاَئِكَةِ لاَ نَدْخُلُ بَيْتًا فِيهِ تَصَاوِيرُ .
