1. When you do a good deed, make sure you know who is benefiting from it; then what you do will not be wasted.
2. You will be repaid for any kindness you show to a devout person. If he doesn't repay you, the Most High will.
3. No good ever comes to a person who gives comfort to the wicked; it is not a righteous act.
4. Give to religious people, but don't help sinners.
5. Do good to humble people, but don't give anything to those who are not devout. Don't give them food, or they will use your kindness against you. Every good thing you do for such people will bring you twice as much trouble in return.
