As for the next 4 Ps of Islamic Marketing, let us take an individual look at each one of them.
Politics - In most of the Muslim nations, political stability is not always guaranteed. They have a volatile history and it would do well for marketers to keep a close tab on the political conditions in their target country.
Public Opinion - While public opinion is important in almost all other cultures, it assumes significant importance when dealing with Muslim nations. Religion is woven so strongly in the Muslim culture, that a negative public opinion can seriously affect a marketer's chances of being successful in that market.
Preaching - Preaching in this case refers to the religious preachers in the Islamic world, i.e. Maulvis. While in other societies, it would not be too much of a worry for marketerers if some religious preacher banned their products. But in the Islamic societies, a fatwa would spell doomsday for any marketer.
Prophet - Prophet in this case refers to the Koran, as recounted by the Prophet. Muslim consumers are very conscious of their religious literature and things which are permissible and not permissible. Hence, products/services which are considered forbidden as per the Koran will be almost impossible to sell in these nations.
