وَعَنِ ابْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا
أَنَّ اَلنَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ فِي اَلَّذِي سَقَطَ عَنْ رَاحِلَتِهِ فَمَاتَ: «اغْسِلُوهُ بِمَاءٍ وَسِدْرٍ، وَكَفِّنُوهُ فِي ثَوْبَيْنِ»
The Messenger of Allah (sallallahu alayhi wa sallam) said concerning the man who fell off his mount and died during Hajj, “Wash him with water and Sidr (lotus leaves) and shroud him in his two garments (that he was wearing for Ihram).” Agreed upon.
