What is the ruling on exposing oneself to people to receive charity?

Question : This is a man who has a father and a mother, and no one to serve them. He works here in the Kingdom, so he brought them over to be with him. He used to take his father to the mosque, and some people would bestow charity upon him, giving it to him. This man then asked someone for a ruling, and he was told that the charity is lawful because he did not take it out of a desire for it or by asking for it. Then, when the father tasted the sweetness of money, he began to insist that his son keep him present in that place. If he did not keep him there, he would speak ill of him with words that I heard, which sometimes reach the level of disbelief. So, after this, should he send him back to his country, where no one is there to serve him, or should he keep him in this state?

Answer : So I say first: Is the charity that was given to him obligatory zakah or voluntary charity?
If it is obligatory zakah, then it is not lawful for him, because he is self-sufficient through his son’s spending on him. But if it is voluntary charity, there is no harm in his accepting it. So we must first look into this aspect before anything else. Then, if it becomes clear that this charity is voluntary and the father is insistent on staying in this place in anticipation of this charity, there is no harm in his accepting voluntary charity, even if in this state he is desiring it. We may say that it is forbidden for him, meaning the father, to sit in this place because of the desire of his soul for it. The Prophet (peace and blessings be upon him) said to 'Umar ibn al-Khattab: . And the solution to the problem, in my view, is that your father stays with you, with your mother, and that you move him from this place to another place, and that you be patient with the harm, cursing, and insults and the like that come from him.
