Questions on the Explanation of the Book of Nullifiers of Islam

Question:
When does the shortening of prayer begin for a traveler? Is it when he passes beyond the buildings, or must he cover a distance of eighty kilometers?

Answer:
If he intends a distance of more than eighty kilometers, meaning eighty kilometers or more, and he intends it when he leaves the buildings, then the shortening of prayer and breaking the fast in Ramadan begin when he leaves the buildings. For at that point he has begun the journey; it is called a journey when one departs and goes out.
