If anyone says Amin [during the Salat (prayer) at the end of the recitation of Surat Al-Fatiha]
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 ".
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! 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)?"
