Zakat means growth, blessings, purification, or appreciation. It is called zakat because one's wealth grows through the blessings of giving part of it and the prayer of those who receive it. Zakat purifies its giver of his/her sins and is clearly ordered by God. The Quran says "Take alms of their wealth and make them pure and clean " (9:103).
There are two main type of zakat:
Zakat al-fitr
This zakat is caused by breaking the fasting at the end of Ramadan. it is sometime called sadaqat al-fitr. Zakat ul-fitr is leived on individual and not on his/her wealth. Zakat ul-Fitr is mandatory for every Muslim, young, old, men, women, free and captive.
Zakat ul-mal
Zakat was instituted among Muslims to carry out a variety of objectives. Islam ordained zakat to achieve, through it, social justice and sublime moral and spiritual values. It is a criterion for the believers and a way to success in this life and the next.
Allah says, "Who establishes worship and spend of that we have bestowed upon them, these are the true believers. For them are grades of honour with their Lord, and forgiveness, and a beautiful provision". [8:3-4]

Therefore Zakat is:
A transfer of possessions and not a favour or a gift, given by the owner to those who deserve it, in accordance with the Qur'an and the Sunnah.
Considered In a Specified Portion of the wealth, determined according to specific principles.
Not due on all types of wealth there are certain conditions that should be fulfilled in order not to pay zakat on one's wealth.
Due on wealth that has fulfilled the nisab . Having this condition ensure social justice and reduces the differences among social classes. It also guarantees sufficient equalization.
Allah has warned those who do not give Zakat that they will face dire consequence. He says, "O you who believe! Verily, there are many of the rabbis and the monks who devour the wealth of mankind in falsehood, and hinder (them) from the way of Allah. And those who hoard up gold and silver, and spend it not in the Way of Allah-announce unto them a painful torment (Quran 9:34).
Zakat improves an individual's social spirit also give true and practical expression of Islamic brotherhood. When Muslims pay zakat, the society becomes like one family. The prophet (SAW), said, "The believers in their mutual kindness, compassion and sympathy are just like one body. When one of the limbs is afflicted, the whole body responds to it with sleeplessness and fever".
Zakat also removes hatred and envy from the hearts of the poor for they know that their right from the wealthy is preserved. The prophet, sallallaahu alayhe wa sallam, said, "The relationship of the believer with another believer is like (the brick of) a building, each strengthens the others".
It improves one's personality also helping other Muslims makes the one more comfortable with his role in the community. He feels victorious over his weakness (like greed) and Satan, who try to keep him/her away from doing good deeds.
