Musnad Ahmad 25:77

Sufyan narrated to us, from ‘Amr, from Sa‘id ibn Jubayr, from Ibn ‘Abbas, who said: We were with the Messenger of Allah (peace and blessings of Allah be upon him), when a man fell from his camel, and it broke his neck, and he died while he was in the state of Ihram. The Messenger of Allah (peace and blessings of Allah be upon him) said: "Wash him with water and lotus leaves (sidr), and shroud him in his two garments, and do not cover his head, for Allah, the Mighty and Majestic, will resurrect him on the Day of Resurrection reciting the Talbiyah (saying 'Labbayk')." And he said once: "He will be saying the Talbiyah."
