The Art of Giving and Receiving

Never will you attain the good [reward] until you spend [in the way of Allah ] from that which you love. (Ayat 92

In order to achieve something, we need to give something. As Newton says' every action has a reaction'; and yet it has proven to be one of the most successful thoughts which have been taught so far- let's come across the wonderful policy of Allah. Even He gives us when we give in the way of Him.

Giving in His way literally doesn't mean to give money to a needy person or help a relative financially; to give in the way of Allah holds a vast meaning. Your smile is a charity to the world. Nobody is responsible for your bad mood. It is your own responsibilty to donate smiles to the creatures of Allah and make them feel special; for if you do not smile you abandon His way.
Allah honoured human beings as the' Ashraf-ul-Makhluqat'- meaning that He made the trees and animals inferior to us. And this certainly holds true keeping the fact in mind that plants do take in water from the land but they return it in the form of vapours which we inhale in. They produce fruits which we eat. So what is the purpose of plants? They are serving us. We are dependant upon them and they don't give us a chance to complain. They are dutiful towards Allah. They have no ego. Not gone astray like us.
Similarly, the formation of crude oil took place when the decomposed animals got dumped into the lava-inner crust of the earth. So animals have been serving remarkable benefits for us too.

If you notice Allah makes things happen in pairs; He made certain parts of plants dependant on each other to perform several functions akin to the physioligical functions of humans and animals. So when it comes to charity, He likes no less of acts which are done in pairs. One action complements another. If you are exchanging a smile with a person so do it with good words; it is not that you insult a person's dignity and cover it up with a smile. If you are donating a loaf of bread to the needy so make sure you do it with a glass of milk so that the poor can swallow it easily.
For Allah says in the Quran:

The charity of those who expend their wealth in the Way of Allah may be likened to a grain of corn, which produces seven ears and each ear yields a hundred grains. Likewise Allah develops manifold the charity of anyone He pleases, for He is All-Embracing, All-Wise. (Surah Baqarah 261)

He knows we are thankless..

Allah has bestowed so many blessings on us. He gave us feet to walk, hands to write and make numerous objects, eyes to see wonderful colours and taste buds to taste several natural fruits in different flavours. To some He gave beautiful eyes, some in shape and some in colour; to some He gave a fair skin with beauty and to some He gave a darker one with more protection from external air. Whilst He gave these countless blessings to us, He knows we are thankless, as illustrated below in His beautiful words:

And We have certainly established you upon the earth and made for you therein ways of livelihood. Little are you grateful. (7:10)

Thanklessness is deep rooted inside us. If it had been not, we would not be running after the Dunya and adapting the West. When we get sad, we tend to commit sins and indulge in activities which are against the Islamic Shariah. Although He keeps us warning again and again in the Book of Guidance, still we are thankless and very little do we remember His blessings.

Follow, [O mankind], what has been revealed to you from your Lord and do not follow other than Him any allies. Little do you remember. (7:3)
