Jahm bin Aws says: I heard Abdullah bin Abi Maryam. Abdullah bin Rustum passed by him in his procession and said to Ibn Abi Maryam: "I wish I could sit with you and talk with you." When he had gone, Ibn Abi Maryam said: I heard Sayyiduna Abu Hurayrah (may Allah be pleased with him) say that the Prophet (peace and blessings be upon him) said: "Do not envy a sinful person for a blessing he has, for you do not know what he will face after his death. With Allah Almighty there is for him a killer (who will keep killing him), and he will not die."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat, and its narrators are thiqat (trustworthy).
