Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah Narrated ‘Aisha (Radi-Allahu ‘anha):

I stuffed for the Prophet (Sallallahu ‘Alaihi Wa Sallam) a pillow decorated with pictures (of animals) which looked like a Namruqa (i.e. a small cushion). He came and stood among the people with excitement apparent on his face. I said, “O Allah’s Apostle! What is 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)?”
