Re: Balance transfer fee or another form Interest?
Brother RIBA is a much wider term, sood is just part of it,RIBA alfazl Riba - is not included normaly in the meaning of sood.
What do you mean by credit cards benefit? is it the principal loan/amount? in that case principal amount is not RIBA but a RIBA based loan on which there is a risk of RIBA.
