The Djinn of Zakat are wealth and Alms giving Djinn. They work in a way that if you are poor they give charity to you. Once the charity is given then and your okay financially they give you pure wealth.
You however MUST give back in return or you will go back to being poor and the Djinn will never work for you again.
Your Djinn has a special name that only you will be given. All these Djinn are human friendly and will be bound to serve you. You will begin by having hard times leave you. You need to do nothing for this. After that is done you will come into money to spare. It is at this time when you can buy what you want and have no fear financially that you must give alms ( charity to the poor). If you do not do this you will go back to being in a bad financial state.
This is very easy and it shows the Djinn your respect for what he did for you. All these Djinns are male.
