Are the father's brothers entitled to claim past rents that the father collected from shops he built on land they own, and what will happen to the shops when the land is sold?

Your paternal uncles are entitled to rent for their share of the land if they did not give you permission to utilize it and build shops on it. If they conceded and remained silent, there is a dispute regarding silence, whether it constitutes permission and a waiver of right or not. Reconciliation and understanding are necessary among all brothers concerning the shared land and commercial shops. This could involve the uncles paying your father the value of his construction, or he pays the value of the land, or they all sell and the owner of the construction is given his right, or some waive their rights for others. Otherwise, the matter must be referred to the judiciary for resolution. There is a disagreement among scholars regarding the issue of someone who built on another's land, whether with or without permission.
