From him, from Muhammad ibn al-Husayn from Ja’far ibn Bashir from Salih ibn al-Hakam who said: I asked Abu Abdillah عليه السلام, peace be upon him, about prayer on a ship. Imam عليه السلام said: “A man asked my father (Imam al-Baqir عليه السلام) about prayer on a ship, and Imam عليه السلام said to him: ‘Do you turn away from the prayer of Nuh عليه السلام, peace be upon him?’” So I asked the Imam عليه السلام: “Shall I take with me a clod of earth to prostrate on?” Imam عليه السلام said: “Yes.”
