What is the ruling on purchasing lands granted by the state whose owner has not yet received the title deed, knowing that they are registered in his name with the municipality and have been transferred to the notary public, and the owner has inspected them?

It is impermissible to sell lands granted by the state before they are received and their ownership is firmly established for the grantee, due to the prohibition against a person selling what he does not own and against gharar (uncertainty) sales. The Prophet (peace and blessings of Allah be upon him) forbade selling what one does not possess and forbade gharar sales, which involve uncertainty in the acquisition of one of the two عوضين (counter-values). Sheikh Ibn Baz issued a fatwa stating the impermissibility of selling land grants before their possession and complete ownership are secured.
