Is it permissible to demand a sum of money to save a person from drowning, for example?

Question:
A questioner says: Your Eminence the Shaykh (may Allah preserve him), peace be upon you and Allah's mercy and blessings. We are a group of four people. One of us went swimming, and he is not a good swimmer, so he said, "Save us!" Of the remaining three, one is a good swimmer, so we told him, "Save our companion." He said, "On the condition that you give me a sum of money." My question is as follows: If we do not give him the money, do we sin? And will he receive the reward if he saves our companion while taking the money? And do we sin if we do not all save him?

Answer:
It is obligatory for everyone to save a Muslim from destruction. It is obligatory for everyone, and without anything. This is his obligation. It is his obligation to save the drowning person without anything. It is not permissible for him to take anything from people, because this is his obligation. Yes. But if he refuses to save the drowning person except for a wage, he is given the wage, and the sin is upon him. The sin is upon him. Yes.
