Kwa kifupi, ujira unapaswa kubainishwa kwa namna inayoondoa kila kutojua kuuhusu, ili utekelezwe ipasavyo bila mzozo, kwa sababu mikataba yote imewekwa awali ili kuondoa migogoro baina ya watu. Kabla ya kuanza kazi, ujira lazima ukubaliwe, na ni makruhu (chukizo) kumtumia mfanyakazi kabla ya kukubaliana naye kuhusu ujira wake. Ikiwa kuajiri kwa kazi kulifungwa kwa mkataba, mfanyakazi anastahiki ujira kwa nguvu ya mkataba, lakini si lazima kumkabidhi mpaka kazi imalizike. Baada ya hapo, unapaswa kukabidhiwa mara moja, kwa sababu ya kauli ya Mtume ﷺ: "Kuna watu watatu ambao mimi nitakuwa mpinzani wao Siku ya Kiyama: mtu aliyetoa ahadi kwa jina langu kisha akafanya hiana, mtu aliyemuuza mtu huru na kula bei yake, na mtu aliyemwajiri mfanyakazi, akapata kazi yake kikamilifu, lakini hakumpa ujira wake," imepokewa na Bukhari kutoka kwa Abu Hurairah. Lakini ikiwa kulikuwa na sharti la kuchelewesha ujira, basi uchelewe hadi wakati wake uliowekwa. Ikiwa sharti linasema ujira ulipwe kwa awamu kila siku, kila mwezi, au chini ya hapo au zaidi ya hapo, basi wakati uliowekwa ni ule ambao pande mbili zimekubaliana. Si lazima mwajiri apate manufaa ya kazi kikamilifu; inatosha kwamba mfanyakazi ajiweke tayari kutumiwa, hivyo ujira unakuwa wa lazima kwa mwajiri. Kwa hiyo, mtu akimwajiri mfanyakazi binafsi amhudumie nyumbani kwake, na mfanyakazi akafika nyumbani kwao na kujiweka mikononi mwake, basi anastahiki ujira kufikia mwisho wa kipindi ambacho angeweza kutumiwa na mwajiri. Ingawa mkataba ni wa huduma ambayo huenda mwajiri asiipate kikamilifu, kumwezesha mwajiri kuipokea hata kama hakuipokea, hii inatosha kwa mfanyakazi kustahiki ujira. Hii ni kwa sababu upungufu unatokana na upande wa mwajiri badala ya mfanyakazi. Lakini kwa mfanyakazi wa kawaida, ikiwa aliajiriwa kufanya kazi fulani, basi ama ataifanya huku kitu hicho kikiwa chini ya mamlaka yake, kama mchoraji anayepaka rangi katika duka lake mwenyewe, na mshonaji anayefanya kazi katika duka lake mwenyewe. Hivyo wajibu wake wa kufanya kazi hautakoma hadi amemrudishia mteja, na hastahili ujira wake hadi amekabidhi baada ya kukamilisha. Hii ni kwa sababu kitu kilichoagizwa kiko chini ya mamlaka yake, na hatakuwa huru na wajibu hadi amekabidhi kwa mteja. Vivyo hivyo, kazi inaweza kuagizwa kufanyika ndani ya eneo la mwajiri, kwa mfano ikiwa mwajiri amemleta mshonaji au mchoraji nyumbani kwake ili kushona au kupaka rangi kwa ajili yake, basi mfanyakazi atakuwa huru na wajibu wa kazi na kustahili ujira wake mara atakapoimaliza, kwa sababu alikuwa chini ya mamlaka ya mwajiri, na hivyo kazi ilikabidhiwa papo hapo.
In short, the wage should be defined in a manner that removes any ignorance about it, so that it can be duly fulfilled without dispute, because all contracts are originally laid down to remove disputes among people. Before starting the work, the wage has to be agreed upon, and it is disliked (Makruh) to use a worker before agreeing with Him over his wage. If the hiring over a work was contracted, the worker is appropriated the wage by the force of the contract, but it is not obligatory to hand it over to Him until the work is finished. Thereafter, it should be immediately handed over to him, due to the saying of the Prophet (pbuh) (pbuh): “There are three persons of whom I am their opponent on the Day of Judgement: A man who gave (a word) in my name then He deceived, a man who sold a free person and devoured his price, and a man who hired a worker where He received (the work) from Him in full and did not give Him his wage”, narrated by Bukhari from Abu Hurairah. But if there was a condition to delay the wage, then it should be delayed to its fixed time. If the condition states that the wage is in instalments daily, monthly, or less, or more than that, then the fixed time is that which the two parties agreed upon. It is not necessary that the employer actually receives the benefit in full, rather it is enough that the worker makes himself available to be used, so that the wage becomes due from the employer. So, if a person hired a private worker to serve Him in his house, and the worker came to their house and put himself at his disposal, then He deserves the wage by the end of the time period in which He could have been used by the employer. Even though the contract is for a service which may not have been fully received by the employer, enabling the employer to receive it even if He did not, this is enough for the worker to deserve the wage. This is because the shortcoming is from the side of the employer rather than the employee. However, for the common employee, if He was employed to work on a certain thing, then He would either do it while it is kept under his authority, like the painter who paints in his own shop, and the tailor who works in his own shop. So his responsibility to do the work will not finish until He has handed it back to the client, and He does not deserve his wage until He has handed it over after completion. This is because the thing contracted upon is under his authority, and He would not be cleared of responsibility until He hands it over to the client. Likewise, the work may be contracted to be done within the domain of the employer, for example if the employer brought the tailor or the painter to his house to sew or paint for him, then the employee would be cleared of the responsibility of the work and deserve his wage once He had finished it, because He was under the authority of the employer, and thus the work was handed over immediately.
