据伊本·哈哲尔在《取舍之光》（Al-Fath）中所述：生活供给（rizq）是指伊玛目从公库（bait al-mal）中拨给那些为穆斯林利益尽责之人的款项。司法审判是允许从公库中为其提供生活供给的职责之一，这是国家为穆斯林利益而雇用他们所执行的职能。凡依照沙里亚受雇从事与穆斯林利益相关的任何工作，无论该工作属于敬拜还是其他性质，都有权获得报酬。其证据是，安拉（SWT）为收取天课的人规定了一份报酬。

Al-Hafiz mentioned in Al-Fath: provision (rizq) is that which the imam appoints from bait al-mal to whoever discharges Muslims interests. Judiciary is one of the tasks which is allowed to obligate provision to it from bait ul-mal, which is a function the State employed them for of the interests of Muslims. Anyone who is employed to undertake in accordance with the shara any work relating to the interests of the Muslims, is entitled to a wage, whether this work was worship or otherwise. The evidence to this is that Allah (S.W.T) assigned a share to those who collect the sadaqah. .

所以祂(SWT)说:

So He (S.W.T) says: .

"以及那些负责征收善款的人。"[TMQ 9:60]。
