Angels do not enter a house in which there are pictures
حَدَّثَنَا يَحْيَى بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنِي ابْنُ وَهْبٍ، قَالَ حَدَّثَنِي عُمَرُ ـ هُوَ ابْنُ مُحَمَّدٍ ـ عَنْ سَالِمٍ، عَنْ أَبِيهِ، قَالَ وَعَدَ النَّبِيَّ صلى الله عليه وسلم جِبْرِيلُ فَرَاثَ عَلَيْهِ حَتَّى اشْتَدَّ عَلَى النَّبِيِّ صلى الله عليه وسلم فَخَرَجَ النَّبِيُّ صلى الله عليه وسلم فَلَقِيَهُ، فَشَكَا إِلَيْهِ مَا وَجَدَ، فَقَالَ لَهُ " إِنَّا لاَ نَدْخُلُ بَيْتًا فِيهِ صُورَةٌ وَلاَ كَلْبٌ ".
Narrated Salim's father: Once Gabriel promised to visit the Prophet (ﷺ) but he delayed and the Prophet (ﷺ) got worried about that. At last he came out and found Gabriel and complained to him of his grief (for his delay). Gabriel said to him, "We do not enter a place in which there is a picture or a dog."
