In a contract of al-kafalah (or al-kifalah), it is the party who provides assurances as to the performance of an original party to a commutative contract or accepts to stand surety. In other words, al-kafeel is the one who joins his liability to that of the principal (al-makful or al-makful anhu) in claims regarding debts, personal injury or material assets.

Al-kafeel is also spelled “al-kafil“.

Al-Kafeel is Arabic for guarantor.
