Another important thing one should follow is donating food to the poor and needy. If somebody comes to you around lunchtime, you should offer food to that person. If we don't have excess food, you should give from what you kept for your consumption. A hungry person will easily get satisfied with whatever we give and he will pray to god for our well being.
That is why a human being will feel that the donation you can give is food to a person who is hungry.
Knowledge is power.
