The beauty of Islam is that nothing is wasted, nothing is meaningless. Giving some water to a thirsty homeless animal can wipe out your sins. Birds and animals eating from plants you grow in your garden is a charity. A compassionate touch on an orphan’s head is appreciated by God. A smile and a good word are praised. Putting a morsel in your wife’s mouth is a righteous deed. Cherishing your own family is a charity. Honoring you parents is highly estimated and rewarded.
