My deceased father has left some money.

Answer

If the deceased had made a wasiyyat (i.e. issued a directive/bequest) for Hajj Badal to be performed for him, then it will be incumbent to have the Hajj performed for him. The expense for the Hajj should be taken from one third of the value of his assets.

If the one third is not sufficient to cover the expenses, then it will not be permissible to take anything more from the estate without the happy consent of all the heirs.

If the deceased had not made wasiyyat for Hajj Badal, then all the assets he left belong to the heirs. Nothing of his money may then be used to perform Hajj Badal.
