Is the prayer valid if a large, undragable ship or an immovable large animal connected by a rope is present?
Chapter on Praying with Impurity and Other Matters
Al-Mughni
Book of Prayer
Primary text
If the ship is too large to be pulled, or the animal is too large to be moved against its will, the prayer is not invalidated because the worshipper is not following or implicitly carrying the object causing the impurity.
