Before deciding a case, ask four questions:
1. Is the retreat vowed and binding, the last-ten-days Sunnah, or merely voluntary?
2. What is the legally recognised place of retreat for this person?
3. Is the exit a recognised necessity or a personal errand?
4. If intimacy occurred, was it contact, ejaculation resulting from contact, or intercourse?
These distinctions prevent one short passage from being applied indiscriminately to every scenario.
