A person sent his father an amount of money to keep it for him as an amanah (trust) until he returns to his country, or to invest it for him (the son). The father bought a piece of land and registered it in his name.
Is it permissible for the son to demand that his father registers the land in his name (the son)? Or is it permissible for him to ask for the money he gave to him? What should he do in this case?
If the reality is as you have mentioned, you should ask for your right from your father in a proper manner except if he is in need of the revenue of the land you gave him. If he responds to you, all praise is due to Allah, and if he is in need of it or of its revenue to spend on himself and those whom he supports, you have no right to demand it from him. The Prophet (peace be upon him) said:
You and what you own are at the disposal of your father.
He (peace be upon him) said this when a man said to him: My father needed my money. He (peace be upon him) also said:
The most pleasant of what you eat is that out of what you earn; and your children are from your earnings.
