Sa’ad, from Musa ibn Umar, from Ali ibn al-Nu‘man, from Mansur ibn Hazim, from Abu Abdillah عليه السلام, peace be upon him, who said: I heard Imam al-Sadiq عليه السلام say: “If you come to a town and firmly decide (azma‘ta) to stay for ten days, then complete the prayer (atimm al-salat). But if a man leaves it (completing the prayer) out of ignorance, then there is no need for him to repeat it.”
