Imam al-Ba’li commented, “It is not permissible for one to betray a contract he made between them because of his betrayal, so he should not defraud him as he was defrauded by him. The Lawgiver forbade betrayal of someone who betrayed him and did not appoint it as a form of retaliation, so he should not take from his money without his knowledge in the amount that he took. This is the sounder opinion of the scholars.”

قال البعلي لا يجوزُ له أن يغدرَ في عقدٍ عقده بينهما لأجلِ كونِه غدره فلا يخونُه كما خانه والشارعُ نهى عن الخيانةِ لمن خان ولم يجعلْه قِصاصًا فلا يأخذُ من مالِه بغيرِ علمِه بقدرِ ما أخَذَه هو وهذا أصحُّ قولَيِ العلماءِ
