This manuscript deals with some interpretive issues related to 'sustainability' when the concept moves ('is translated') from conventional to Islamic economics. To this aim it raises some critical remarks on possible hermeneutical mistakes in asserting an immediate convergence between the former and the latter through sustainability. Accordingly the text warns the readers that the operativity of Islamic social finance does not correspond precisely to those of SDGs: on the contrary, it is grounded on a different paradigm of socio-economic inclusion derived from Islam, of which the interpret must be conscious when pursuing objectives of sustainable development and shared prosperity.
