Those who administer charity  Those who administer charity – based on concurrent standards – include institutions and organisations responsible for it, and their relevant bodies responsible for collecting charity from the wealthy and sharing out among the poor according to legal standards.

They are trustworthy, such that the charity wealth is preserved with them unless in the case of forceful abduction or carelessness. The one giving charity has absolved his responsibility by giving it to them. Hanbalis have explicitly mentioned this, and it is the decision of the Islamic Fiqh Academy as part of the Organisation of Islamic Cooperation, as well as being legally advised by the fourth symposium held for modern legal charity matters. are categorised into three:
The first category: are the collectors. Those are the ones whom the ruler gave the responsibility to travel across the land and sea to collect charity from its owners.
The second category: are the caretakers who preserve the wealth of charity collected.
The third category: are those who share it out among those who legally deserve it.
Fourthly: If the Administrator is Wealthy
The one who administers charity is given from it even if he is wealthy. Consensus has been quoted on this by: Ibn `Abd al-Barr, al-Kasani, and al-Buhuti.
Fifthly: The Amount Taken by the Administrator
The administrator is given the amount of a wage unconditionally. This is the position of the majority: Malikis, Shafi`is, and Hanbalis.  It is permissible for the Hanbalis that the ruler sends someone without a contract and then gives him a gift later, and if he wishes he may contractually agree a certain amount, and if he wishes, he may set a condition based on a particular action, such that if the worker accomplishes it, he deserves the amount.
It is not permissible to gift extra money to the administrators of charity, as all that is gifted is for status. Consensus has been quoted on this by Ibn `Abd al-Barr and Ibn Raslan.
