Sahih Muslim Book - 37, Hadith - 5525

حَدَّثَنَا مَنْصُورُ بْنُ أَبِي مُزَاحِمٍ ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ ، عَنِ الزُّهْرِيِّ ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ ، عَنْ عَائِشَةَ ، قَالَتْ: دَخَلَ عَلَيَّ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَنَا مُتَسَتِّرَةٌ بِقِرَامٍ فِيهِ صُورَةٌ ، فَتَلَوَّنَ وَجْهُهُ ، ثُمَّ تَنَاوَلَ السِّتْرَ فَهَتَكَهُ ، ثُمَّ قَالَ: إِنَّ مِنْ أَشَدِّ النَّاسِ عَذَابًا يَوْمَ الْقِيَامَةِ ، الَّذِينَ يُشَبِّهُونَ بِخَلْقِ اللَّهِ.

It was narrated that 'Aishah said: "The Messenger of Allah (s.a.w) entered upon me and I had hung up a thin curtain on which there was an image. His face changed color, then he tore down the curtain and said: 'Among the people who will be most severely punished on the Day of Resurrection will be those who imitate the creation of Allah.'"
