It has been explained that by Aamil, is referred to that person who will be the khalifah of the time after Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam. It is also said that it is that person who collects and brings the harvest of the lands. i.e. who is in charge and manages the lands. It is possible both are intended here. The Baytul Maal is responsible for the salary of the khalifah, and every person responsible for managing the affairs also has the right to take his share of the estate. It is not necessary that it be in the form of Dinars and Dirhams (currency). For example it is mentioned that, if it is said money should not be distributed, that other things are included. Or it is said the, the distribution is always according to the value of the articles, in which case it shall always be referred to in terms of money.
