I have a question about offensive Jihad. Does it mean that we are to attack even those non-Muslims which don't do anything against Islam just because we have to propagate Islam?

You should understand that we as Muslims firmly believe that the person who doesn't believe in Allah as he is required to, is a disbeliever who would be doomed to Hell eternally. Thus one of the primary responsibilities of the Muslim ruler is to spread Islam throughout the world, thus saving people from eternal damnation.

Thus what is meant by the passage in Tafsir Uthmani, is that if a country doesn't allow the propagation of Islam to its inhabitants in a suitable manner or creates hindrances to this, then the Muslim ruler would be justifying in waging Jihad against this country, so that the message of Islam can reach its inhabitants, thus saving them from the Fire of Jahannum. If the Kuffaar allow us to spread Islam peacefully, then we would not wage Jihad against them.

and Allah Ta'ala Knows Best
