ماذا أفعل إذا هددني الدائن بالذهاب إلى الشرطة لعدم دفع فائدة الدين؟

It's better to give her her money only.

If she goes to the police and claimed the same scenario as you explained herewith, both of you will end up in jail for breaking Sharia law regulations for giving and receiving loans from individuals with interest.

It falls under the criminal act of the UAE under Usury rules. But if she claimed the principal amount only and never mentioned the interest part, she might oblige you to pay her all the principal.

If you did pay her any amounts before, they will be deducted from the total amount she is claiming.
