Al-Matalib al-'Aliyah 825 — Burial

It is narrated from Abd al-Hakam bin Sulayman that when the "Plague of al-Jarif" (that is, the terrible epidemic which swept people away like a flood) broke out, Bushayr bin Ka'b (may Allah have mercy on him) dug a grave for himself (as preparation for death), then he sat in it and kept reciting the Noble Qur'an until he completed it; then, when he died, he was buried in that same grave.
Imam Ahmad bin Hanbal (may Allah have mercy on him) recorded it in his work "al-Zuhd".
