حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ: حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ، عَنْ عَبْدِ اللهِ بْنِ عُثْمَانَ بْنِ خُثَيْمٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ
قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «عَلَيْكُمْ بِالْبَيَاضِ مِنَ الثِّيَابِ، لِيَلْبِسْهَا أَحْيَاؤُكُمْ، وَكَفِّنُوا فِيهَا مَوْتَاكُمْ، فَإِنَّهَا مِنْ خِيَارِ ثِيَابِكُمْ»
The Messenger of Allah (sallallahu alayhi wa sallam) said (sallallahu alayhi wa sallam): “You should acquire white clothes, so that your living ones may wear them, and you can shroud your deceased in them, for they are among the best of your clothes.”
