Al-Husayn ibn Sa’id, from Hammad ibn Isa, from Mu‘awiyah ibn Wahb, from Abu Abdillah عليه السلام, peace be upon him, who said: Imam al-Sadiq عليه السلام said: “If you enter a town and you intend to stay for ten days, then complete the prayer (atimm al-salat) as soon as you arrive. But if you intend to stay less than ten days, then shorten (the prayer, ‘fa-qassir’) until a month has passed. When the month is complete, then complete the prayer.” He (ibn Wahb) said: “I asked, ‘I entered a town on the first day of the Month of Ramadan, and I did not intend to stay for ten days.’” Imam عليه السلام said: “Shorten (the prayer, ‘qassir’) and break your fast (aftir).” I asked: “I continued in that state, saying, ‘Tomorrow (I will leave)’ or ‘the day after tomorrow,’ and so I broke my fast for the whole month and shortened (the prayer).” Imam عليه السلام said: “Yes, the two are the same; if you shorten (the prayer), you also break your fast, and if you break your fast, you also shorten (the prayer).”
