Chapter on the Prayer in the Ship

From him, from al-Hasan ibn Mahbub from Abu Walad who said: I said to Abu Abdillah عليه السلام: “I had gone out from Kufah on a ship to Qasr Ibn Hubayrah, and it is about twenty farsakhs from Kufah by water. So I travelled that day, shortening the prayer. Then in the night, I decided to return to Kufah, and I did not know whether I should pray on my return with shortening or with full (prayer)? What should I do? Imam عليه السلام said: “If you had travelled on the day you departed, a distance of one ‘barid’, then it was upon you, when you returned, to pray with shortening (the prayer), because you remained a traveller until you reached your home.” Imam عليه السلام said: “And if you did not travel a distance of one ‘barid’ on the day you departed, then it is incumbent upon you to make up every prayer you performed that day with shortening (the prayer), with full prayers, before you move from that place. This is because you did not reach the location in which shortening is permissible before you returned. So it is obligatory upon you to make up what you shortened. And when you return, you must perform the prayer in full until you reach your home.”
