Jihad as social activism

The Complete Idiot’s Guide To Understanding Islam
Part 3, Chapter 14, page 167:

There are many levels of jihad. An important part of our daily life as Muslims is to strive (or “make jihad”) to improve society. Judaism has its concept of Tikum Olam or perfecting the world, and many other religions have a similar idea. The key phrase for us comes from the Qur’an, which says that Muslims must “encourage good while forbidding evil.” Thus, Muslims must be active in the social affairs of any community they live in…

Islam is a proactive way of life, meaning we are taught to get involved and take action int eh defense and promotion of the truth. Why should Muslims try to get involved in the welfare of the society around them? Quite simply because God said, “You are the best community brought out of humanity. You encourage what is right and forbid what is wrong and you believe in Allah.” (Qur’an 3:110) That is quite a defining statement!
