Jahm bin Aws narrated that I heard Abdullah bin Abi Maryam, and Ubaidullah bin Rustam passed by him on his mount. He said to Ibn Abi Maryam, "Indeed, I desire your company and to converse with you." When he left, Ibn Abi Maryam said: I heard Abu Hurairah (may Allah be pleased with him) saying that the Messenger of Allah (peace and blessings be upon him) said: "Never envy a wicked person because of his blessings, for you do not know what he will encounter after his death. Surely, for him with Allah is such a killer that never dies." This hadith reached Wahb bin Munabbih, so Wahb sent Abu Dawood A'war to him and said: "O so-and-so, who is that killer who never dies?" Ibn Abi Maryam said: "Death."
