(( قَدِمَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ سَفَرٍ وَقَدْ سَتَّرْتُ عَلَى بَابِي دُرْنُوكًا فِيهِ الْخَيْلُ ذَوَاتُ الأَجْنِحَةِ ، فَأَمَرَنِي فَنَزَعْتُهُ . ))
((Allah's Messenger (ﷺ) came back from the journey and I had screened my door with a curtain having portraits of winged horses upon it. He commanded me and I pulled it away.))
