Narrated Ibn `Abbas: While a man was riding (his Mount) in `Arafat, he fell down from it (his Mount) and broke his neck (and died). The Prophet (ﷺ) said, "Wash him with water and Sidr and shroud him in two pieces of cloth, and neither perfume him, nor cover his head, for he will be resurrected on the Day of Resurrection saying, 'Labbaik,' (i.e. like a pilgrim)."

حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهم ـ قَالَ بَيْنَمَا رَجُلٌ وَاقِفٌ بِعَرَفَةَ إِذْ وَقَعَ عَنْ رَاحِلَتِهِ فَوَقَصَتْهُ ـ أَوْ قَالَ فَأَوْقَصَتْهُ ـ قَالَ النَّبِيُّ صلى الله عليه وسلم " اغْسِلُوهُ بِمَاءٍ وَسِدْرٍ، وَكَفِّنُوهُ فِي ثَوْبَيْنِ، وَلاَ تُحَنِّطُوهُ وَلاَ تُخَمِّرُوا رَأْسَهُ، فَإِنَّهُ يُبْعَثُ يَوْمَ الْقِيَامَةِ مُلَبِّيًا ".
