People who are true fasting would try to avoid unlawful actions, because if the deed was done, fasting is not worth at all. This is what disabdakan Prophet Muhammad, "Many people are fasting, do not get the value of nothing, except hunger and thirst alone."

The scope of Islamic economics is very broad, covering the scope of conventional economics. Because of that, the economy is not just limited to Islamic banking and financial institutions, but also about the production, distribution and consumption is also on monetary, fiscal, management, accounting and so on. The entire Islamic economics should we actualize it in daily life as the practice of Islamic law in the field of muamalah.

At present, we need to do an evaluation and critique of our current behavior in the conduct of fasting. The way we look at any of Ramadan needs to be clarified. Phenomenon that occurs during Ramadan is the occurrence of excessive kosumsi pattern, namely the purchase of food, drinks, fruits that cost excessive relatively more expensive than usual days.

Fasting and consumer behavior
First of all, fasting must give birth every living being simple and efficient in consumption. Simple life attitude, efficient and not redundant in the month of fasting, see the teachings of Prophet Muhammad when fasting. The Prophet taught that the iftar meal with just a sip of water and eating a date. Attitudes and behavior when it almost disappeared from the lives of Muslims, especially in Indonesia.

We have had a habit of cultivating Muslim food, beverages, fruits, all kinds of cakes, porridge, compote and iftar event that shows the attitude sidup israf and tabzir. This behavior is clearly contrary to the Sunnah of the Prophet and the Islamic sharia.

Very anti-Islamic attitudes extravagant life or mubazzir, because the devil are brothers mubazzir. Islam teaches a simple life attitude in consuming goods and foods. In the Qur'an Allah says firmly, "Eat and drink ye, but not extravagant. Truly Allah loves not those who exaggerated."

Israf and tabzir behavior not only contrary to the sharia or the Sunnah of the Prophet, but also showed attitudes individualistic and selfish, because when we apply israf consumption patterns (excessive), many of our brothers that the economic crisis that is very sad. And if we can save, then the rest of the money could be used to infak or charity to the poor who need funds for a decent life.

Not to mention that Ramadan is over, some are busy buying new clothes, prepare the cake and drinks for Lebaran and recreation plan for Lebaran. This consumer behavior that Muslims should be corrected gradually.
