(19) باب الْكَفَنِ فِي ثَوْبَيْنِ
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)."
