Sa’d bin Abdullah narrated from Ya’qub bin Yazid, from Muhammad bin Shu’ayb, from Abu Kahmas: I was present at the death of Isma’il while Abu Abdullah عليه السلام was sitting beside him. When death had approached him, Abu Abdullah عليه السلام tied his jaw, closed his eyes, and covered him with a shroud. Then Imam عليه السلام ordered preparations for his burial. When the preparations were completed, Imam عليه السلام brought the burial shroud and wrote on its edge: "Isma’il testifies that there is no god but Allah سبحانه وتعالى."
