哈里发应当过问瓦里（Wali）的所作所为，并对其严加监督。他可以亲自进行，也可以委派他人去考察他们的情况并进行巡查。穆阿温（Mu’awin）也被允许监督其所协助哈里发的那一地区的瓦里们的行为，并应将其所了解的情况以及他就此所作的决定，与哈里发共同审议，正如在授权辅佐官的职责中所阐明的那样。如此，哈里发便能了解各位瓦里的状况，并跟进其局势。他还应不时地与全体或部分瓦里会面，倾听民众对他们的申诉。

The Khalifah should inquire about the actions of the Wali and should monitor them closely. He should do this directly or appoint someone who would check their state of affairs and carry out inspections. The Mu’awin is also allowed to monitor the actions of the wulah in the wilayat that he helps the Khalifah in, and he should review his findings and decisions he took regarding them with the Khalifah, as has been explained in the task of the delegated assistant. Thus, the Khalifah would be aware of the states of the wulah, and following their situation. He should also meet with all of them or some of them from time to time and listen to the complaints of the subjects against them. .

已经证实，安拉的使者（愿主福安之）在任命总督时会考察他们，正如他对穆阿兹和艾卜·穆萨所做的那样。他还会向他们讲解应如何履行职责，正如他对阿慕尔·本·哈兹姆所做的那样。他也曾提醒他们注意一些重要事项，正如他任命阿班·本·赛义德为巴林总督时对他所做的那样，并对他说：

It has been confirmed that the Messenger of Allah (PBUH) used to examine the Walis when appointing them, as he did with Muadh and Abu Musa. He used to explain to them how they should conduct their duties, as he did with amr b. Hazm. He also drew their attention to some important matters as he did with Aban b. Sa'id when he appointed him Wali over Bahrain and said to him: .

“照看‘Abd Qays，尊重他们的领袖”。

"Look after ‘Abd Qays and honour their leaders". .

同样,也有确凿记载表明,他(PBUH)曾要求各地的总督(Walis)接受问责,考察他们的情况,并聆听关于他们的各种报告。他(PBUH)还曾要求总督们交代所收取的税款和所支出的费用。

Likewise it has also been confirmed that He (PBUH) used to hold the Walis accountable, inspect their situation and listen to news brought to him about them. He (PBUH) used to ask the Walis to account for the revenues and expenses used. .

布哈里和穆斯林在阿布·胡迈德·阿尔-萨伊迪的传述中说：他说：安拉的使者ﷺ委派伊本·阿尔-乌特比耶为白努·萨利姆的天课征收官。他回来见先知ﷺ时说："这是给您的，而这是别人送给我的礼物。"于是安拉的使者ﷺ说：

Al-Bukhari and Muslim narrated on the authority of Abu Humaid Al-Sa'idi who said:. The Messenger of Allah (PBUH) appointed Ibn al-Utbiyya as ‘amil in charge of Sadaqah of Banu Salim. When he returned back to the Prophet (PBUH), he said: "This is for you and (this is a gift) that was presented to me.” So the Messenger of Allah (PBUH) said:.

"你既说实话，为何不留在父母家中，好让你的礼物送到你手上呢？"欧麦尔（愿真主喜悦他）经常密切监督各地的总督（Walis），并派穆罕默德·本·麦斯莱迈（Muhammad Ibnu Maslamah）去考察他们的状况、检查他们的工作。欧麦尔每逢朝觐季节便召集各地总督，审查他们的施政表现，听取民众对他们的申诉，也与他们商讨各地的政务，并询问他们自身的状况。据传，欧麦尔曾对身边的人说："如果我为你们任命了你们中最优秀的人，并命令他公正行事，你们会认为我的职责就算尽到了吗？"他们说："是的。"他说："不，直到我检查了他的表现，看他是否照我的命令去做，我的职责才算尽到。"欧麦尔以严格问责各地总督和官员而著称。他甚至会在没有确凿证据的情况下，仅凭怀疑就罢免某些人；有时对一名总督的疑虑甚至还达不到怀疑的程度，他也会将其罢免。有一天有人就此问他，他说："更换一位长官，以便改善民众的事务，这是很容易的。"［布哈里，《圣训实录》，第6979则］

"Why did you not remain in your father’s and mother’s home so that your gift comes to you if you said the truth." ‘Umar (ra) used to closely monitor the Walis, and he appointed Muhammad Ibnu Maslamah to examine their state of affairs and inspect them. ‘Umar used to gather the Walis during the Hajj season to review their performance and to listen to the complaints of the subjects about them, and he also used to discuss with them the affairs of the Wilayah's and ask about their own conditions. It has been reported that ‘Umar once said to people around him: “Would you say that my duty would be fulfilled if I appointed over you the best from amongst you, and ordered him to be just?” They said, “Yes”. He replied, “No. Not until I had checked his performance, and seen whether or not he did what I had ordered him to do.” .‘Umar was known to be strict when accounting the Walis and the amils. He would even remove some of them on a suspicion without conclusive evidence, and he even used to remove a Wali on the slightest doubt that did not even reach the level of suspicion. He was asked about this one day and he said, “It is easy to swap an Amir for another so as to amend the people’s affairs.” [Bukhari, Sahih. #6979] .

然而，尽管他对官员们要求严格，却给予他们充分的自主权来履行职责，并维护他们在治理中的威信。他常常倾听他们的意见，并认真考虑他们的论点。如果他认同某个论点，便毫不羞于表明自己的赞同和信服，事后还会对该官员大加赞扬。 有一天，关于他在霍姆斯的官员乌迈尔·伊本·萨阿德的消息传到了他的耳中。乌迈尔曾在霍姆斯的讲坛上说：“只要政权强大，伊斯兰就会保持强盛。而政权的强大并非依靠刀剑的杀戮或鞭子的抽打，而是依靠以真理裁决和维护公正。”听到这番话后，欧麦尔说：“我真希望能有一个像乌迈尔·伊本·萨阿德这样的人来帮我处理穆斯林的事务。”

However, despite his strictness with them he gave them a free hand to undertake their duties and safeguarded their reputation in ruling. He used to listen to them and consider their arguments. If he liked an argument he was not shy of showing his approval and conviction of it and of showering the amil with praise afterwards. One day news reached him about his amil over Homs Umayr Ibnu Saad who had said while over the pulpit of Homs, “Islam will remain strong as long as the authority is strong. And the strength of the authority does not come about with the killing by the sword or the lashing by the whip, but by judging with the truth and the upholding of justice.” Upon hearing this ‘Umar said, “I wish I had a man like Umayr Ibnu Saad to help me with the Muslims' affairs.” .
