Claiming the right of pre-emption after a long time has passed

Question:
I said: Honorable Shaykh, may Allah grant you success, if a man sells his share in a property to another man, and the partner of this man does not claim the right of pre-emption until a long time has passed since the sale, does the partner have the right of pre-emption after that?

Answer:
It has been narrated to us, and it has come to us, that one of the conditions is that one must claim the right of pre-emption immediately upon learning of it. If he delays it without an excuse, he has no right of pre-emption. This is one of the conditions of the right of pre-emption: that it be claimed immediately. If the request is delayed without an excuse, he has no right of pre-emption. Yes.
