Is the land on which a house was built for residential purposes considered a gift to the son, given the presence of male and female siblings, and the father's refusal to accept monetary compensation for it?

If your father granted you the land by way of ownership due to your need, then there is no harm in it. However, if he granted it to you without justification, then this is not permissible according to the preponderant opinion. And if he granted it to you by way of a loan, then upon his death, it reverts to the heirs.
