Consider your rights as well as that of the other in the maintenance costs
Fatwa No: 7608

Question

My profession is based on experience and practice. For example, if it happens that I come across a defect in a very expensive electric appliance, I can fix it by discovering the defect that might be very simple but which nonetheless requires knowledge of the theory of operation, as well as experience, to discover. Also, I might design an electric circuit for it that costs me very little money. How could I estimate the cost of maintenance?

Answer

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu 'alyhi wa sallam, is His slave and Messenger.

 

Your question is one of a person who seeks the pleasure of Allaah and avoids transgressing the limits He has set. We supplicate to Allaah The Almighty to grant you His pleasure and acceptance.

 

In this case, you can calculate the cost of the materials which you put in place of the damaged parts, in addition to the fees that you deem suitably rewarding for your effort in the work and for thinking of a way to fix the defect. You should consider the following in estimating the return of your work:

Avoid deceiving, exploiting, and extorting the person who pays you for the maintenance. Allaah The Almighty Says (what means): {O you who have believed, do not consume one another's wealth unjustly but only [in lawful] business by mutual consent. And do not kill yourselves [or one another].} [Quran 4:29] The Prophet, sallallaahu ‘alayhi wa sallam, said: “It is not lawful to take the wealth of a Muslim unless he gives it willingly.” [Al-Bayhaqi]
Consider the benefit of the other party just as you consider yours. Ash-Shaatibi said in Al-Muwaafaqaat, “It is necessary for anyone seeking an allowable benefit to consider the rights of Allaah and the rights of people.”

Do not harm the other party by charging him what is too much for him to pay. The Prophet, sallallaahu ‘alayhi wa sallam, said: “There should be neither harm nor malice.” [Maalik] [Mursal (Disconnected)]

Therefore, do not harm either yourself or anyone else, so that Allaah would bless what you earn.

 

Allaah Knows best.
