Sunan an-Nasai
أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، عَنْ يَزِيدَ، - وَهُوَ ابْنُ زُرَيْعٍ - قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي جَمْرَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ : جُعِلَ تَحْتَ رَسُولِ اللَّهِ صلى الله عليه وسلم حِينَ دُفِنَ قَطِيفَةٌ حَمْرَاءُ .
It was narrated that Ibn 'Abbas said: "When the Messenger of Allah was buried, a red velvet cloak was placed beneath him."
