While a man was standing at ‘Arafāt, he fell from his mount and it snapped his neck. So, the Messenger of Allah (may Allah's peace and blessings be upon him) said: Wash him with water and Sidr, and shroud him in his two garments, and do not perfume him or cover his head, for he will be resurrected on the Day of Judgment reciting Talbiyah (Here I am, O Allah, at Your service!)

While one of the Companions was riding his mount at ‘Arafāt in the Farewell Pilgrimage, he fell from it, broke his neck and died.
The Prophet (may Allah's peace and blessings be upon him) ordered them to wash him with water and Sidr, as the dead are normally washed, and to shroud him in his upper and lower garments which he had worn for Hajj.
Since the man was in the state of Ihrām and the traces of worship were still visible on him, the Prophet (may Allah's peace and blessings be upon him) forbade them from perfuming him or covering his head. He justified that saying that he would be resurrected in the same state he died upon, which was the state of reciting Talbiyah, the slogan of Hajj.
