The impermissibility of selling shares in the real estate bank to another person

The questioner: A man registered his name with the bank to carry out construction, and after several years he sold his name. What is the ruling on this action?The Shaykh: If a person applies to the real estate bank to build a house for himself, it is not permissible for him to withdraw from this request unless the bank agrees; because if the door were opened for people to manipulate this,It is said to this man: If you are now in no need of the construction,Or if you have changed your mind, go to the bank and say: they will cancel my name, and if you are in need, then rely on Allah and complete the journey.

The questioner: Is it not permissible, O Shaykh?The Shaykh: No, selling is not permissible; because you have only the right of usufruct. So if you benefit from what you registered your name for, otherwise leave it.
