Muhammad ibn Yahya, from Ahmad ibn Muhammad ibn Isa, from Ibn Faddal, from Abdillah ibn Bukayr, said: I asked Abu Abdillah عليه السلام, peace be upon him, about a man who is in Basra while he is originally from Kufa, and he has a house and residence there. He passes through Kufah, and he is only passing by, not intending to stay except for the duration needed to prepare himself, for a day or two. Imam عليه السلام said: “He stays on the outskirts of the city and shortens (the prayer).” I asked: “And if he enters his family’s home?” Imam عليه السلام said: “Then it is upon him to perform the full prayer.”
