Inheritance of inheritance 4575364385

Three sons of Master Abdur Rauf. He established his two eldest sons by reading and writing and by sending them abroad. But he couldn't do much for the little boy. Therefore, at the time of his death, he called his wife and bequeathed five acres of land adjacent to Biswaroad to his youngest son. The older boys could not tell because they were abroad. Later they heard and said, as our younger brother we will cooperate with him overall. However, I cannot give him the inherited property of my ancestors alone. Now the question is, does this will have to be fulfilled? Will there be any problem to disobey this will? 7477662135
