In consumption, the consumer's choice is based on the individual's rationale which is guided by self-interest. Rational economic man will assess their decision by using pain and again assessment. Their main goal is to maximize gain and minimize pain. 


A few things that we learned from our class with Dr Nahar the other day was first on how the economy is guided by the "dollar voice". It is when the things that were produced in the market are according to what those who have more dollar wants. The one who has a lot of money are the minority but their voice is heard in the market. This had resulted in products that are produced in the market do not meet the demand for all. The example that was given by Dr Nahar was on the type of houses that are available in the market nowadays, most of them are condominiums, bungalows, and apartments that only the rich can afford and these had left with the underprivileged ones to have no choice for a good place to live in and some even end up living under the bridge just to have a roof above their head.


Next, Dr Nahar also explained how we should actually divide our income in order to sustain ourselves. Dr mentioned about the 1/3 rule where we should divide 1/3 of our income into consumption, 1/3 to pay the debt and the remaining 1/3 should be put into savings and investments.

Basically, in consumption, Islam taught us to be moderate while in it. Shari'ah had provided a limit on how we should consume which is by not being greedy, stingy, wasteful and excessive and consuming.
