Ask the person as to the purpose of seeking money. If it is for food or clothes or medicine, try to buy such items by yourself and give to them( if you can afford).
If the purpose is to meet daily needs, better guide him to either find some works to earn with own efforts or approach a social service organisation who will have permanent solution to such poor people.
Never ever help a person with money as it becomes a habit involving laziness and carelessness.
