What should one do if impurity occurs during prayer and cannot be removed?

If impurity occurs during prayer, then if the worshipper is able to remove it during prayer, he should do so. Otherwise, he must interrupt the prayer, remove the impurity, and then resume it if possible. However, if he is unable to remove the impurity after interrupting the prayer, then he proceeds with his prayer and there is nothing upon him; because avoiding impurity is a condition dependent on knowledge and ability.
