What is interest? Is there any difference between interest and Riba?

The origination of term interest dates back to 17th century with the emergence of banking system at global level. Interest means giving and/or taking of any excess amount in exchange of a loan or on debt. Hence, it carries the same meaning/value as that of Riba as defined in the previous question. Further, it is narrated that “the loan that draws interest is Riba”.
There is consensus among the Muslim scholars of all the fiqhs that interest is Riba in all its forms and manifestations.
