Musnad Ahmad 12007

Translation

✧ The Prophet ﷺ entered one of the gardens of Madinah belonging to Banu al-Najjar and heard a voice from a grave. He asked about it: "When was this person buried?" They said, "O Messenger of Allah, he was buried in the pre-Islamic era." He was pleased by that and said, "Were it not that you would not bury one another, I would have prayed to Allah [Mighty and Majestic] to make you hear the punishment of the grave."
