Father selling some of his
possessions to one of his sons
Question

                Is it permissible for a man
      to sell something that he owns to one of his sons, knowing that some of
      them are able to make the purchase whilst others do not have anything and
      cannot make the purchase?
Praise be to Allah.It
      is permissible for a man to sell some of his property to one of his sons,
      if he (the son) is able to make the purchase, and he should deal with him
      as he would deal with a stranger. He should not give him any preferential
      treatment that would indicate that he favours him over his siblings.
