بَابُ إِذَا قَالَ أَحَدُكُمْ آمِينَ. وَالْمَلاَئِكَةُ فِي السَّمَاءِ، فَوَافَقَتْ إِحْدَاهُمَا الأُخْرَى، غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
Sahih al-Bukhari 3224

Narrated `Aisha:

I stuffed for the Prophet (ﷺ) a pillow decorated with pictures (of animals) which looked like a Namruqa (i.e. a small cushion). He came and stood between the two doors and his face began to change. I said, "O Allah's Messenger (ﷺ)! What did we do wrong?" He said, "What is this pillow?" I said, "I have prepared this pillow for you, so that you may recline on it." He said, "Don't you know that angels do not enter a house wherein there are pictures; and whoever makes a picture will be punished on the Day of Resurrection and will be asked to give life to (what he has created)?"

حَدَّثَنَا مُحَمَّدٌ، أَخْبَرَنَا مَخْلَدٌ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، عَنْ إِسْمَاعِيلَ بْنِ أُمَيَّةَ، أَنَّ نَافِعًا، حَدَّثَهُ أَنَّ الْقَاسِمَ بْنَ مُحَمَّدٍ حَدَّثَهُ عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ حَشَوْتُ لِلنَّبِيِّ صلى الله عليه وسلم وِسَادَةً فِيهَا تَمَاثِيلُ كَأَنَّهَا نُمْرُقَةٌ، فَجَاءَ فَقَامَ بَيْنَ الْبَابَيْنِ وَجَعَلَ يَتَغَيَّرُ وَجْهُهُ، فَقُلْتُ مَا لَنَا يَا رَسُولَ اللَّهِ‏.‏ قَالَ ‏"‏ مَا بَالُ هَذِهِ الْوِسَادَةِ ‏"‏‏.‏ قَالَتْ وِسَادَةٌ جَعَلْتُهَا لَكَ لِتَضْطَجِعَ عَلَيْهَا‏.‏ قَالَ ‏"‏ أَمَا عَلِمْتِ أَنَّ الْمَلاَئِكَةَ لاَ تَدْخُلُ بَيْتًا فِيهِ صُورَةٌ، وَأَنَّ مَنْ صَنَعَ الصُّورَةَ يُعَذَّبُ يَوْمَ الْقِيَامَةِ يَقُولُ أَحْيُوا مَا خَلَقْتُمْ ‏"‏‏.‏
