Chapter: What should be done with a Muhrim if he dies?

باب مَا يُفْعَلُ بِالْمُحْرِمِ إِذَا مَاتَ ‏
Sahih Muslim 1206 d

Ibn Abbas (Allah be pleased with them) reported that a person proceeded along with the Messenger of Allah (may peace he upon him) in the state of Ihram and fell down from his camel and his neck was broken, and he died. The Messenger of Allah (ﷺ) said:

Bathe him with water mixed with lote (leaves) and shroud him in two (pieces of) cloth and do'not cover his head for he would come on the Day of Resurrection pronouncing Talbiya.
وَحَدَّثَنَا عَلِيُّ بْنُ خَشْرَمٍ، أَخْبَرَنَا عِيسَى، - يَعْنِي ابْنَ يُونُسَ - عَنِ ابْنِ جُرَيْجٍ، أَخْبَرَنِي عَمْرُو بْنُ دِينَارٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، - رضى الله عنهما - قَالَ أَقْبَلَ رَجُلٌ حَرَامًا مَعَ النَّبِيِّ صلى الله عليه وسلم فَخَرَّ مِنْ بَعِيرِهِ فَوُقِصَ وَقْصًا فَمَاتَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ اغْسِلُوهُ بِمَاءٍ وَسِدْرٍ وَأَلْبِسُوهُ ثَوْبَيْهِ وَلاَ تُخَمِّرُوا رَأْسَهُ فَإِنَّهُ يَأْتِي يَوْمَ الْقِيَامَةِ يُلَبِّي ‏"‏ ‏.‏
