Fasid

Fasid names an act or contract sound at its root but flawed in one attached condition.

What it means for me: Fasid usually leads to the same outcome as batil: the arrangement has to be undone. The label mainly matters for working out the details of undoing it.

Example: One scholar calls a deal fasid; another calls the same deal batil. Both agree it cannot stand, so the useful question is what happens to the money now, not which label is correct.

Do not confuse with: Batil, void. The majority use the two words for the same thing. The Hanafi school keeps fasid for a sound contract carrying one flawed condition.

If scholars differ: The majority hold fasid and batil describe the same defect. The Hanafi school distinguishes them: fasid describes a contract sound at its root but flawed in one condition, unlike batil. See know the ruling before you sign.
