Islam and Culture

وَما أَرْسَلْناكَ إِلاَّ رَحْمَةً لِلْعالَمِين
We have not sent thee, O Muhammad, but as a mercy for all human beings "(Surat al-Anbiya: 107)

Islam is a religion for the whole of nature, without distinction of race, skin color, economic status and other. This is evidenced by the word of Allah in the Qur'an:
In an institution must have rules that differ from one another. Likewise, Islam also has rules that are already enshrined in the Qur'an and Hadith of the Prophet.
Al Quran is a product of Allah  that should not be changed by anyone, even though the prophet.
Medium hadith are sayings, deeds, and assessments or actions companions of the Prophet who is left by the prophet.
Culture is the result of human creative works based on the mind. And this mind is strongly influenced by the environment, so that what is considered good by a particular society is not necessarily good for the community to another.
This is what distinguishes between culture and religion. But if religion wherever and whenever that is considered both by the religion is good, although sometimes by the human mind is considered not good.
For example, if a bad sector in a region considered gambling, but maybe in other areas would probably assume it's okay. But if we see the religious side of this  would be considered bad (evil deeds), why: 
1. Creating a lazy work
   People who like to gamble usually tired of thinking why should work if it will be to multiply the money from his gambling 

2. Make confict
People who lose will usually be thinking how he get back items that he bet. So it is not rare to encounter a lot of murders in the area of gambling
 
3. Justifies any ways
Obtaining goods and get back bets that folded a lot of rethinking of this course by a gambler. No matter whether by stealing, robbing and even killing though.
