Sahih Bukhari Volume 1, Book 8, Hadith 374

حَدَّثَنَا أَبُو مَعْمَرٍ عَبْدُ اللَّهِ بْنُ عَمْرٍو، قَالَ حَدَّثَنَا عَبْدُ الْوَارِثِ، قَالَ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ صُهَيْبٍ، عَنْ أَنَسٍ، كَانَ قِرَامٌ لِعَائِشَةَ سَتَرَتْ بِهِ جَانِبَ بَيْتِهَا فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ أَمِيطِي عَنَّا قِرَامَكِ هَذَا، فَإِنَّهُ لاَ تَزَالُ تَصَاوِيرُهُ تَعْرِضُ فِي صَلاَتِي ‏"‏‏

Narrated By Anas : 'Aisha had a Qiram (a thin marked woollen curtain) with which he had screened one side of her home. The Prophet said, "Take away this Qiram of yours, as its pictures are still displayed in front of me during my prayer (i.e. they divert my attention from the prayer)."
