3.Ibn Abī ʿUmayr narrated from Abū Ayyūb, from Abū ʿUbaydah who said, “I said to Abū Jaʿfar , ‘May I be your ransom! Inform me of something that I may benefit from.’ So he said, ‘O Abā ʿUbaydah, remember death often, for a person does not remember death often but that he detaches himself from the [yearnings of the material] world.’”
