Batil

Batil names an act or contract lacking a pillar or condition of its formation, producing no legal effect.

What it means for me: Batil means there is nothing to preserve. Whatever changed hands gets returned, and the situation is treated as though the contract never existed in the first place.

Example: A man learns, months later, that a contract he signed was void from the start. His question becomes how to unwind it and return what was taken, not whether he was rewarded for keeping it.

Do not confuse with: Fasid, defective. The majority treat the two as one meaning. The Hanafi school reserves batil for a missing pillar and fasid for a flawed condition.

If scholars differ: The majority treat batil and fasid as synonyms in transactions. The Hanafi school separates them: batil is a defect in the contract's basic elements, fasid a defect in one attached condition. See know the ruling before you sign.
