Bequest of 'Life Interest' in Muslim law is

Muslim law does not split the ownership of the corpus into English-style life estates, but it allows interests limited in time to be created in the usufruct. A bequest of a life interest, that is, of the use and income of property for the legatee's life, is therefore valid; the Privy Council in Nawazish Ali Khan v. Ali Raza Khan (1948) recognised such limited interests in the usufruct.

It is not void or voidable; on the legatee's death the property passes to the person entitled to the corpus.
