باب مَا يُفْعَلُ بِالْمُحْرِمِ إِذَا مَاتَ ‏
Sahih Muslim 1206 a

Ibn Abbas (Allah be pleased with them) reported that a person fell down from his camel (in a state of Ihram) and his neck was broken and he died. Thereupon Allah's Apostle. (ﷺ) said:

Bathe him with water mixed with the leaves of the lote tree and shroud him in his two (pieces of) cloth (Ihbram), and do not cover his head for Allah will raise him on the Day of Resurrection Pronouncing Talbiya.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَمْرٍو، عَنْ سَعِيدِ بْنِ، جُبَيْرٍ عَنِ ابْنِ عَبَّاسٍ، - رضى الله عنهما - عَنِ النَّبِيِّ صلى الله عليه وسلم خَرَّ رَجُلٌ مِنْ بَعِيرِهِ فَوُقِصَ فَمَاتَ فَقَالَ ‏ "‏ اغْسِلُوهُ بِمَاءٍ وَسِدْرٍ وَكَفِّنُوهُ فِي ثَوْبَيْهِ وَلاَ تُخَمِّرُوا رَأْسَهُ فَإِنَّ اللَّهَ يَبْعَثُهُ يَوْمَ الْقِيَامَةِ مُلَبِّيًا ‏"‏ ‏.‏
