The beauty of Islam is that nothing is wasted, nothing is meaningless. Giving some water to a thirsty homeless animal can wipe out all your past sins. Birds & animals eating from plants you grow in your garden is a charity. A compassionate touch on an orphan’s head is appreciated by Allmighty Allah. A smile & a good word are praised. Putting a morsel in your wife’s mouth is a righteous deed. Cherishing your own family is a charity. Honouring your parents is highly estimated and rewarded.
Even your pains, physical and emotional, great & small, nothing of them is wasted and meaningless, all are counted and compensated. This is the nature of having a trade with Allah Allmighty, The most generous.
