The ruling on agreeing on the wage after the work is completed
Machine translationRead the Arabic original
The questioner:
Honorable Shaykh, I sometimes need a plumber, and I ask him to fix this thing for me, but I do not agree with him on a wage. After he finishes, I start bargaining with him over the price, and he accepts what I give him. Is this permissible, or must we agree from the beginning?
The Shaykh:
The default is that agreement is required, and if no agreement is reached, he is entitled to the wage of his like.
The questioner:
Honorable Shaykh.
The Shaykh:
You sit and bargain with him after the work is done.
