Findings – This study suggests wastage of the resources because of their economic obsolescence and on the cost of future generation is not allowed in the system of Islam and ultimately decrease the social welfare level. Research limitations/implications – A dynamic cum marginal input-output table can be constructed on the basis of this framework and formulate the socio-economic policy. Originality/value – This research is beneficial to the researchers, policy makers and social scientists for the enhancement of the level of social welfare through this model.
