Islam is present in daily life due to the five-time call to prayer by the Muezzin.
The mandatory daily five-time prayer behind this is adhered to in the western region by only a few believers. Islam is perceived strongest during Ramadan, when many believers fast and give up alcohol and smoking.

Islamic rules for business life, such as the prohibition of interest, are not common in Turkey. Also, the amount of people who insist on the observance of the five-time prayer while at work, is comparatively small.
This is not least due to the fact that in Islam, performing work is considered to be service to God. Only in the fasting month of Ramadan is the effect of religion on business life noticeable: Efficiency and motivation are affected, which has an effect on economic productivity. Traffic becomes a real problem during the period of fasting due to the irritability of the fasters, especially during rush-hour.

The traditional circumcision of boys at a young age is one of the most important religious rituals in Turkey. The circumcision, also known as Sünnet, symbolises the transition from an infant to a boy. The Hamam (Turkish Bath) is an important part of Islamic bathing culture in Turkey. Superstitions, for example, in the form of the protecting eye (nazar boncuğu) or the belief in certain rules ("if the dogs howl at night, someone will die") are rife. The first business of the day (siftah) means a lot to the trader and is therefore conducted at a very good price.
Often, the trader will request that the money be thrown onto the floor.
